What is an old man to do? Play golf, ok maybe once a month. Play cards? same thing when I am in Vegas and want to BS with the world traveller in the Mirage...so trading (actually managing ones finances) is a pastime for anyone who has a pot to piss in. No brainer, 'till I drop or get incapacitated.
Actually many on this board have a skewed view on what trading is....
trading is not by the seat of your pants, starring at a computer 24/7. For some trading is being in the market. So you can do other stuff at the same time and enjoy life.
