Well, my lungs (all five lobes) at age 82, are filled with bone. This is caused by dendritic pulmonary ossification, extremely rare orphan disease generally diagnosed in autopsies. I have no clue what my VO2 max is but I feel very lucky that I can swim 45 minutes, bicycle a couple of hours, the resistance exercises, stretch and walk all in one day. There is no cure, but on the other hand it's not terribly progressive. So I don't worry about my VO2 max, I just hope to get out of bed everyday.<br />
