I bump my head into all kinds of things without noticing. My gf saw me bump my head on a hanger 3 times in 3 minutes and just looked at me in utter disbelief. “What!” “You knocked into that 3 times!!!! What’s wrong with you!”

Hahaha!

I guess that shows that you can be pretty focused, once you'r in the flow ;<)

I hit my head every now and then, but usually in stupid ways ( like wanting to jump outside, then jump too soon and hitting the door post hard ). This happened recently and made me fall backwards and almost injure my back on some steps. I sure felt that head collision and almost had a concussion.

Good to know you halted the retreat of your hair loss. I got plenty ( haven't had a haircut since June ) so if you ever want to lend some...
