I am 25 years old male, play lot s of sports, quit smoking 15 days ago, drinks 3-4 times a week ( in moderation) eats somewhat healthy, no drugs but occasional marijuana. Long horrible heart problems on one side of the family. Grandmother, grandfather dead heart attacks, one aunt near brain dead heart attack, uncle dead at 35 of heart attack and another aunt quadruple bypass surgery just in time. I live a relatively healthy lifestyle! Should I be concerned??
