So how will you know when your common sense is gone? Seems to me common
sence would indicate that you and I both are imperfect and that neither of
us is prepaired for each and every possible accident that might happen in
the future. Commen sense tells me that I am imperfect, I can make a
mistake, and that I may not know that I am no longer capable untill I do
something that may lead to an accident.

I have, over the years, accumulated some bit of knowledge of the function of
the human mind. My minor in college was psychology and my interest in the
subject has continued ever since. I have read all of Steven Pinker's tomes
as well as those of several other authors whose expertise on the subject
attracted my attention. As I have approached my more mature years it has
occurred to me that it would be wise to study the effects of aging. As
such, I have acquired some notion of the tribulations for which I felt wise
to prepare. I do not approach the afflictions of aging blindly.
You are obviously possessed of some of the problems that age will cause or
you wouldn't have expressed your concern in the matter.
Self awareness can be a valuable asset in addressing potential pitfalls. I
like to believe that I am somewhat "self-aware".
In addition, I have a son who visits my shop regularly. He has no
reservations about offering constructive criticism. G
I already have plans for the day I will sell or otherwise dispose of my shop
equipment and undertake other activities that interest me.
My other hobbies include photography, RV travel, reading and writing.
Your concern and advice is, as always, appreciated.
