You come out Lilliputian-sized?
Sore/tired legs could be because of hard ground, old shoes, low iron, need for magnesium. Or work/life balance!
I'm trying to cover iron and magnesium with supplements. Shoes new just before Christmas and I've been rotating them with olds. ( But they have certainly lost their spring.)
I wonder about just getting older.
Re shrinking - the change room shrunk not me.
I guess you were aware of that ...
