It's better to be LUCKY than to be SMART...
I have been fortunate to inherit youthful, healthy genes from my father. To this day  wear the jeans twice a month. I was lucky enough to receive ethics and morality training from my mother. I practise them twice a month too. So there !
All the rest I consider part of my Health Plan. I part at the furthest point from the Library door...100 paces. Then another 100 paces to my corner, upstairs to plug into the WiFi. Surely during he day, to visit the loo, another 100 paces...so y'see how I keep in shape.
When I had my hips replaced, years ago, my friend Al advised "Walk as soon as y'can...as far as y'can."
Al was my Go-To guy on things medical. (A hypochondriac to be sure...but knowledgeable.) I started a day later walking to the mailbox, for the daily deluge of charity appeals. I recall his wise advice every time I walk there today. Thanks Al.
I fully believe that Al is watching over me from Heaven...and even plays little tricks on me for amusement.
Al was always playful that way. Verrry funny Al. Verrry funny.
And each time I fold myself in half to enter or leave my Miata I consider it my Exercise Program. Four or five times a day. AND...it saves me $300 on a gym membership. A DOUBLE win!
So far..so good. No aches, no pains, no joint problems.  And Schnapps Vincit Omnia. Grazie Deo.
