There is alot of bad 'science' floating about. If a drug works for you, then it's better than the long term consequences, If it doesn't then change it. If you can change something by diet/exercise then great, if it's genetics, then you are a bit stuck.
I only went for a checkup a year ago as a good mate had just dropped dead. Heart attack whilst cycling, in hospital, couple of stents, back out, dead the next weekend - literally dropped dead at home.
