The blessing for almost all living things is that we don't really know when or how our 'end' will be (except for a few who, unfortunately will know...).
The blessing of youth is the awareness of that end is almost completely pushed well below consciousness.
The blessing of age is an increased awareness and appreciation of even the smallest things and goodness around us.
Time, and with it change, seems to accelerate with age. It's difficult to keep up.
For me, I've found that being 'persistent' has always stood me in good stead.
Do what you can and in such fashion to acknowledge your spirit.
Ride On
