When I stand with my feet together and reach upwards with my left arm, I can just touch the ceiling. When I use my right arm, I am about 1cm short of the ceiling. I wonder why this is? The other main difference between my arms is that the right one is a lot more muscular from years of playing tennis and other sports. Can playing tennis inhibit the growth (lengthwise) of your dominant arm?
I noticed this fact several years ago but I only just thought of creating a thread about it.
yes, my left arm is slightly longer than my right. mine is because i have damaged the rotator cuff in my left shoulder so my arm doesn't sit in its socket properly. hopefully when it's healed it will be back to normal
