Belt, suspenders and physical bodily change

Several people have told me they too find they are not as tall as they were.  The book "Man Overboard" by Dr. Craig Bowron, MD is about aging, especially in men.  It describes aging as an 'extractive' and 'reductive' process.  We who have aged some have experienced that side of aging that is 'redistributive', the deal where some of my lovely muscles have fallen into my pants.  

I was once measured to be 5 feet, 5 inches, not a glorious height for a man, but better that 5'3" that I have shrunk to.  

Now, when I take a seat, my belly expands quite a bit.  Then, when I stand, it shrinks.  If I loosen my belt as I sit to accommodate my greater girth, I can embarrass myself if I fail to close my belt again as I stand up.  Some men cease depending on their waist and a belt and switch to suspenders and their shoulders instead.  I have some suspenders but haven't switched yet.
