Just telling in advance, English is not my forte, lol. I'm a math person. :-)
Anyways, what I'm inferring from the poem is this:
The human body, of course, gets older, but usually the mind of an older person is coherent and wise. Yet, the older body has its own "conscientiousness". A consciousness that understands the body's frailty but knows that it can still accomplish tasks it had once before; these tasks are achieved with the patience of a mule but with the intensity of a lion. Rushing or hastening seem to be incomprehensible... Still, the aged body knows more than it begets. Life happens all around yet there isn't a desire to change what happens. Wisdom and experience has seeped in over the years... Aging... An invaluable awareness that affects everything alive wins in the end over the aged body. Nails, hair, and skincare become obsolete. The old body, free from constraints, expresses the validity of its existence with boldness and courage. The wrinked skin and gray hair, impossible to avoid, but difficult to obtain, outshines the youth the body once had. For once, and only once, boundaries don't exist... Only the hope of sharing the struggles and victories that occur in a lifetime, the experiences unique to the aged body... The hope that the aged body can bestow unto others the gloriousness of the aged body.
Hope that helped. Good luck.
