I'm 43. My father had had his third heart attack by the time he was my age. Shitty diet, smoking during more of his life than not, negligible exercise (despite being an adrenalin junkie), and high-stress work (during my life, he was everything from a paramedic, to an underwater welder, to a corrections officer at a state penitentiary) were doubtless contributing factors. I'm sure genetics played a substantial part, too. Given all that, it's something I've been pretty paranoid about since his death (motorcycle accident). My cardiovascular health, however, seems to be a bullet dodged: my BP is pretty consistently about 110/70, my resting heart rate is in the low 50s, and my 1-minute heart-rate recovery is always at least 40.
