my late significant other had a five bypass surgery a couple of years before i met him...he could dance all night, bench press 340 lbs, and was as strong as an ox...his heart was fine but he died in a terrible fall....now the methods are even better..he had the full cracking of the chest type but he told me he went dancing two weeks after the surgery. that might have been a bit too macho
the point is, try not to let fear get in the way and have faith that when God wants you He will come and get you, and if it is not your time, you will be around for us to pamper for the forseeable future.
