Good afternoon Sqad !
Would the fact that the sole of black peoples feet being just about the only part of the body that is white (ish) have anything to do with the incidence of skin cancers on that part of the body ?
At this time of year, I need to put factor 50 on my right arm, and especially my right hand, if I am going to driving for any length of time. If I don't then the very thin skin on my right hand becomes extremely inflamed and very sore, sometimes even bleeding. This can happen after only 2 hours driving.
I already have multiple brown "liver spots" there, which make me look considerably older than my 61 years !
On the very occasionally times that I am driving in the American West, especially the deserts of California and Arizona, it effects my left hand and arm !
I am sure that I have heard that northern hemisphere immigrants to Australia have a high incidence of skin cancer. My nephew now lives in Sidney and he has told me of lots of people he knows that have have these MMs removed. I wonder what the incidence of MMs are amongst the Aboriginal population...they have especially black skins it would seem to me.
