Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

2. What is Cataract?
• Cataracts are changes in clarity of the
natural lens inside the eye that gradually
degrade visual quality.
• Clouding that develops in the crystalline
lens of the eye or in its envelope (lens
capsule), varying in degree from slight to
complete opacity and obstructing the passage
of light
3.
4. Cause
• The lens is made mostly of water and protein.
Specific proteins within the lens are
responsible for maintaining its clarity. But as
we age, some of the protein may clump
together and start to cloud a small area of the
lens. This is a cataract, and over time, it may
grow larger and cloud more of the lens,
making it harder to see. The following causes
are...
5. • Ultraviolet radiation from sunlight and other sources
• Diabetes
• Hypertension
• Obesity
• Smoking
• Prolonged use of corticosteroid medications
• Statin medicines used to reduce cholesterol
• Previous eye injury or inflammation
• Previous eye surgery
• Hormone replacement therapy
• Significant alcohol consumption
• High myopia
• Family history
6. Types of Cataract
• A subcapsular cataract occurs at the back of the lens.
People with diabetes or those taking high doses of
steroid medications have a greater risk of developing a
subcapsular cataract.
• A nuclear cataract forms deep in the central zone
(nucleus) of the lens. Nuclear cataracts usually are
associated with aging.
• A cortical cataract is characterized by white, wedge-
like opacities that start in the periphery of the lens and
work their way to the center in a spoke-like fashion.
This type of cataract occurs in the lens cortex, which is
the part of the lens that surrounds the central nucleus.
7. Who usually gets affected by Cataract?
• While cataracts are often associated with
aging, there is no hard and fast rule as to who
gets them. They can form in adults as early as
age 40. They can also affect babies and small
children. In some cases, they are hereditary.
8. How to prevent getting Cataract?
• The standard cataract surgical procedure is typically
performed in either a hospital or in an ambulatory surgery
center. The most common form of cataract surgery today is
a process called phacoemulsification. With the use of an
operating microscope, your surgeon will make a very small
incision in the surface of the eye in or near the cornea. A
thin ultrasound probe is inserted into the eye that uses
ultrasonic vibrations to dissolve (phacoemulsify) the
clouded lens. These tiny fragmented pieces are then
suctioned out through the same ultrasound probe. Once
the cataract is removed, an artificial lens is placed into the
same thin capsular bag that the cataract occupied.
This intraocular lens is essential to help your eye focus after
surgery.
9. There are three basic techniques for cataract surgery:
• Phacoemulsification: This is the most common form of cataract removal as
explained above. In this most modern method, cataract surgery can usually be
performed in less than 30 minutes and usually requires only minimal sedation
and numbing drops, no stitches to close the wound, and no eye patch after
surgery.
• Extracapsular cataract surgery: This procedure is used mainly for very
advanced cataracts where the lens is too dense to dissolve into fragments
(phacoemulsify) or in facilities that do not have phacoemulsification
technology. This technique requires a larger incision so that the cataract can be
removed in one piece without being fragmented inside the eye. An artificial
lens is placed in the same capsular bag as with the phacoemulsification
technique. This surgical technique requires a various number of sutures to
close the larger wound, and visual recovery is often slower. Extracapsular
cataract extraction usually requires an injection of numbing medication around
the eye and an eye patch after surgery.
• Intracapsular cataract surgery: This surgical technique requires an even larger
wound than extracapsular surgery, and the surgeon removes the entire lens
and the surrounding capsule together. This technique requires the intraocular
lens to be placed in a different location, in front of the iris. This method is
rarely used today but can be still be useful in cases of significant trauma.
10. Complications of Cataract Surgery
• While cataract surgery is one of the safest procedures available with a high rate of
success, rare complications can arise. Your ophthalmologist will discuss the specific
potential complications of the procedure that are unique to your eye prior to
having you sign a consent form. The most common difficulties arising after surgery
are persistent inflammation, changes in eye pressure, infection, or swelling of the
retina at the back of the eye, and retinal detachment. If the delicate bag the lens
sits in is injured, then the artificial lens may need to be placed in a different
location. In very rare cases, the intraocular lens moves or does not function
properly and may need to be repositioned, exchanged, or removed. All of these
complications are extremely rare but can lead to significant visual loss if left
untreated; thus, close follow-up is required after surgery.
• In some cases, within months to years after surgery the thin lens capsule may
become cloudy, and you may have the sensation that the cataract is returning
because your vision is becoming blurry again. This process is termed posterior
capsule opacification, or a "secondary cataract." To restore vision, a laser is used in
the office to painlessly create a hole in the cloudy bag. This procedure takes only a
few minutes in the office, and vision usually improves rapidly.
11. How to avoid/ Prevention of Cataract
• At present, there is no real effective way to prevent the
formation of cataracts, so secondary prevention involves
controlling other eye diseases that can cause cataracts and
minimizing exposure to factors that promote cataracts...
• Wearing sunglasses outside during the day might reduce
your chances of developing cataracts or having problems
with the retina. Some sunglasses can filter out UV light,
reducing exposure to harmful UV radiation and might slow
the progression of cataracts.
12. • Some people take vitamins, minerals, and herbal
extracts to decrease cataract formation. No scientific
data prove that these remedies are effective. No
topical or oral medications or supplements are proven
to decrease the chance of developing cataracts.
• A healthy lifestyle might help, just as a healthy lifestyle
helps prevent other diseases in the body. Eat a proper
diet, get regular exercise and rest, and do not smoke.
• If you have diabetes, tight blood-sugar control can
delay the otherwise accelerated development of
cataracts.
