Oh darn, my camera slipped and my whole body got in frame! You guys don't think my friends who use reddit will see right? I'd be pretty embarrassed and all...
It took me until my 50s to stop being self-conscious about my slender body and skinny arms. Exercising more helped a bit but it was mostly in my head. My advice - love yourself now! (The sign was for a Twitter pro-nudity campaign)
