I never needed my back scratched, until one day I did. You can get that flexibility back by stretching it every day, eventually, it will come back. I never knew I lost it.
It's back! The flex stretch is in the rotation of daily stretches.
Glad to hear you never lost it.
I have weird arms and legs and can still do the 'Full Lotus' Yoga position (thought it hurts a bit now), without ever doing Yoga. Maybe I inherited this from one of my parents.. I should ask.
I am truly impressed.
Flexibility depends on genetics and is somewhat inherited. Toss in factors like age, body bulk, and physical fitness. Flexing and stretching as you do certainly helps keep it at the level that it is.
Let's face it. You are blessed. ;)
