|Proof that I'm getting smaller ... these glasses used to fit perfectly ... man, I'm a nerd!|
However, most things I read blamed losing inches off of your stature simply on old age. A 2011 Wall Street Journal article explains that as we age, we actually shrink in size about 1/3" per decade. The article attributes it to the discs compressing, arches falling, and abdominal mass become much less dense which leads to poor posture and gives the appearance of a reduction in height.
So, does running make you shrink? I dunno. But I don't plan on stopping anytime soon. So if you ever actually meet me in person, you might be surprised at just how short I am. But take my word for it, I was once a strapping 6' 2" young man! But this old, shorter guy could outrun that dude every day of the week - ha!
... be great today!
