Lost a friend on Friday. 45ish. Had a heart attack (widow maker) but survived. Took steps to get better, but less than a year later he's dead. Don't wait to care for your health. I started at about 50. But I feel I was a bit ahead of the curve due to my California health nut wife. I had no warning signs and good testing numbers when I started. Just pudgy and didn't sleep well. Now my numbers are better, I'm 35 lbs lighter, and I sleep like a rock. But I'm not taking it for granted. Time for the next step.
