seriously,walk into any trading firm in long island or NYC and just take a look at the guys trading. they are all out of shape and ugly,i'm not kidding. i think stress and poor diet are the two main culprits. before anyone bash's me,i don't mean to come across as shallow but damn,these guys look horrible. fat and bald who smoke and eat potato chips for lunch. i think its irresposible and shows a lack of discipline which is why most traders fail. just my 2 cents.
