You can barely find a healthy person of any age, let alone a 75-year-old. Everybody has their own damages and weak places, and Mark talked multiple times about having metal things in his body and whatnot, even joking about it, and his recent health status is pretty visible, so I can't understand those saints who again can't discuss it because it's personal. So far, I have not seen anything in this thread that would violate Mark's private life in any way, shape, or form. Just people caring about a famous person they admire.
