As a trader, there is a lot of ups and downs in the market, you could loose all your capital in less than a minute with just a very little analytical mistake. The importance of living healthy cannot be overstated to reduce especially the risk of stroke, hypertension or a heart attack which are all long term effect of the accumulated stress gathered from constantly monitoring the market charts, sitting for long hours and increased palpitations and heightened blood flow, which are all situations that full time traders experience.
Always try to give yourself enough time to rest, exercise and maintain a healthy diet as well a social life. All this activities help reduce stress both mentally and physically.
Please!!! I believe that one becomes passionate when one spends a long time exercising a certain activity and believes that because one individually goes through certain emotions or reads that certain people go through the same emotions, this is normal.
One can die for the conditions mentioned in the OP not only for doing trader, there are so many high risk professions, where stress is a cause of death that doing trader should definitely not be even close, but it is that not even close to all the medical complications that you mention.
But if it is your case or that of any other person, nothing of what you recommend is going to save your life, simply dedicate yourself to something else, stroke, heart attack, etc are pathologies with very complex clinical backgrounds, nobody who even suspects that may suffer from some of these pathologies should spend hours in an activity that causes them.
