2. From Rabbi Ben Ezra (Robert Browning,
1864)
Grow old along with me!
The best is yet to be,
The last of life, for which the first was
made.
Our times are in His hand
Who saith, “A whole I planned,
--Youth shows but half;
Trust God;
See all nor be afraid.
4. The Vacant Chair
The Rocking Chair is vacant by the window in the sun,
The knitting is forgotten, the mending not begun,
For Grandma on her motor bike is zooming here and there,
As happy as a lark, as free as the air.
There’s no one in the kitchen baking ginger bread,
Grandma’s at the Gym learning karate instead.
If you need a baby-sitter, for Grandma do not look,
She is busy at the typewriter writing a new book.
Grandma got tired of sitting half the day,
So she goes to the studio to practise ballet.
If you’re down by the river believe what you are seeing
Grandma is down there going water skiing.
And just to fill out her day (I’m not romancing)
Grandma has joined a class to learn belly dancing.
Oh, Grandma is a Darling; I don’t mean to knock her,
I’m merely trying to tell you Granny’s off her rocker!
5. More Poetry about Aging
Confound not the distinctions of thy life which nature hath divided; that is,
youth, adolescence, manhood, and old age: nor in these divided periods,
wherein thou art in a manner four, conceive themselves but one. Let every
division be happy in its proper virtues, nor one vice run through all. Let each
distinction have its salutary transition, and critically deliver thee from the
imperfections of the former; so ordering the whole, that prudence and virtue
may have the largest section. --Sir Thomas Browne (1605-
1682)
If I did not keep telling myself my age over and over again, I am sure I should
scarcely be aware of it. Although every hour of the day I tell myself, “My poor
fellow, you are seventy-three and more,” I cannot really persuade myself of
it. --Andre Gide
i’d rather learn from one bird how to sing
than to teach ten thousand stars how not to dance
--e.e. cummings
6. In short, the best thing to do is behave in a
manner befitting one’s age. If you are 16 or
under, try not to go bald. On the other hand, if
you are over eighty, it is extremely good form to
shuffle down the street clutching a brown paper
bag and muttering, “The Kaiser will steal my
string.” Remember, everything is relative—or it
should be. If not, we must begin again.
--Woody Allen
7. Conversion
He was a born loser, came back, marked
accident-prone too; “Moved, left no
never won a lottery, address.” And it was
married a girl who his car that was cited
couldn’t cook, broke for speeding
his leg the day before from among a flock of others
the wedding going 60 in a
and forgot the ring. 55 mile zone.
He was the kind So it was a real shocker
who ended up behind a post when he found himself
in almost any auditorium. Planes elected chosen by Grace
he was booked to fly on for Salvation, felt
were delayed the exhilaration of

with sickening regularity. Unexpected Joy
His holidays at the beach and tasted, for the
were almost always first time, the Glory of
ruined by rain. All being on
his apples turned out the winning side.

Take a moment to look at the table: I left out most of it.
•What is the time left to live for the total US population at birth? for
males and females? What is the time left to live at age 65?
•Why is your life expectancy higher if you live to be 65 than it is from
birth?
•Why might Hispanics have a longer life span than Whites? This is
known as the Hispanic paradox.

• Life expectancy and life span
– Life span: Maximum number of years an
individual can live
• Between 120 - 125 years
– Life expectancy: Number of years that the
average person born in a particular year will
probably live
– Differences in life expectancy across countries
• Factors such as health conditions and medical care
• Ethnic differences

75 to 80 times
• Age makes cells less capable of dividing

• Biological theories of aging
– Free-radical theory: People age because normal

decay of mitochondria

hormonal system can lower resistance to stress
