It is important to invest in one's physical capabilities. We know that our strength will diminish with age. Something frightening would be to not be able to get up and walk without aid because of lack of strength. I would hate to be trapped by my own body. We don't need to become athletes. We merely need to be able to perform physical tasks.
One sign that I have noticed is a 5 gallon water jug that I used to be able to lift by the neck with one hand now requires me to use the proper handle, or use both hands. My grip is not strong enough to hold it by the neck anymore. This is principally because my job has become more sedentary. I no longer need to rely on strength for my job.
This is one of my largest fears and why I count myself lucky with the stroke. I told the nurse in hospital that if she sees me having a fit or attack and it looks very bad, throw me out the window.
It is depressing to have the feeling of ability, only to have reality remind that it is feeling alone.
