A healthy body is helpful and useful at every juncture and advisable to maintain but try as we may, sooner or later the structure will sag and wither.
That is your faith.
So, you'll receive what you believe.

For me personally, ive got some age on me, and in the last 13 yrs of "Lifting" where ive paid strict attention to what is happening to my body, i can tell you that ive only gotten stronger, and more healthy.......not less.
I expect nothing to change about that reality.., and tomorrow, at 1:15 am, i'll get up, do my 1 hour and 15 mins of stretching and light weights, and then i'll go to the gym, and do 1 hr and 30 mins MORE... of real weight lifting that includes 65-lb (25.5 kg) dumbbells per hand, and cable machines and barbells, and ............etc.
My advice to the reader..
Join a gym, go 3-4 times a week, and watch what happens when you give your body a chance to "restore".
And dont forget the good water, and the good diet, and the required supplements.
"The Science of Good Health", is proven..
