In all seriousness - does running cause you to shrink in height? I ask as I always remember being measured at 5'11 and a bit (the bit is important!), and it was noticed by my mother last weekend that I had in fact shrunk in comparison to my dad and my brother. I was always taller than them. (sulks) I am aware that with age, apparently we shrink, but given that dad is older than me, he'd further shrink and I'd remain taller than him - relatively speaking. My mum then said, in an 'I told you' sort of way - "it's all because of that running you do. You've compressed your bones". I'd like to know if there could be any truth to this - Oh! and no jokes about it stunting my growth!.
