Appreciate your positive attitude!It is never too late at any age to work to fix anything ............ all it takes is a want - many do not want nor care, simple stick head in sand and move forward.
As I tell my kids in class ....two kinds of workers ......
those that do
and
those that watch those that do ..........
But at 75 my outlook is a bit different. I defer to the younger ones...just personally though.
No objection to anyone doing anything they see as helping make life better for the planet and its inhabitants. I guess for me it is just a balance with how I spend my remaining time...
Edit: that almost sounds morbid. Did not mean it that way...just that there are only so many hours left when you get older, the number which nobody knows until after the fact.
