It is a testimony on how to age in good health and
How to deal with injuries and the millions of age-related complications.
Take Wes, Oldtimer, CoachisBack, and they will tell you that getting older is extremely difficult, especially when you have been bodybuilding, but to last this long and be able to go on stage is truly incredible.
Don't look at it like you would look at the horrible Bhank who will die before the age of 50 but if one day you reach 60 you will probably be in poor health and then you will realize that this performance is crazy.
