One of our trader friends suffered a heart attack and we friends went to see him....this trader friend was very conservative...doing delivery type trading...his wife said he never does speculation ( she meant like you people ) ...no tension ...but see he got an attack...after his wife went inside one of us says " yar yehi to problem hai....you never traded F & O....so your heart is not conditioned to absorb shocks....now ferget the medicines...start trading 500 or 700 NF every day....you will never get any heart problem as your heart will get conditioned by blows every day ....if you want stronger medicine...trade BNF"
