Umm, there is SO much I could say here, but I’ll refrain.
I was at work the other day and noticed something very peculiar in that my left forearm was way bigger than my right. No kidding at all, I am right handed, use my right hand for the majority of heavy movement at work, my left hand is only used for programming machines and sometimes parts movement. I usually walk around 6 miles a day, sometimes as much as 18 miles, and I am swinging my arms while walking so the only thing I can come up with is that it is a result of wearing heavy watches on my left wrist. Either that or I am some kind of freak! Picture is of my actual forearm, no photoshoping what-so-ever.
