I am 6-0 145 and can probably run rings around most men half my age. But I also take blood pressure meds, asthma meds and suffer from periodic acid reflux.
Would you say that I'm healthy ? Technically, I have three diseases.
Yet, I'll bet that the average person would look at me and think that, based on my age, my slim build and performance has me looking like the picture of health. In fact, people are often astonished when I tell them how old I am.
