Gambling has a long history dating back to 1300 BC and comes in many forms like dice, cards, horse racing, sports betting, and casinos. While Las Vegas is typically associated with gambling, the global gambling industry is now worth $125 billion with Macau surpassing Las Vegas as the world's largest gambling center. Gambling can be enjoyed recreationally but also carries risks like addiction which affects around 5% of gamblers by increasing dopamine release. It is important to remember that riches won gambling can also be lost, so people should only gamble with what they can afford to lose and know when to walk away.
