All the men in my family closest to me, including my dad and both grandfathers, have died of cardiac arrest.
Knowing that up to 60 percent of susceptibility to heart disease can be attributed to genetics, I started exercising a few times a week in college in an effort to lower my own risk. I’ve kept it up for decades and now engage in 30 minutes of aerobic exercise daily. What I didn’t realize when I started was that exercising would also substantially lower my risk for developing certain cancers.
