Can you still day trade as you get older?

Ditto, just to round out the OP's request.

 

look at Bob Bright. He must be in his 60s. still trades and is a legend

 

In reality, I used to be able to watch the tape on 6 stocks 8 or 10 years ago without a problem. Today, I can only watch 3 or maximum of 4 stocks at the same time which also results in lower daily volume...
