You said it! I have been in outside sales for over 20 years. Guess where my problems started ? The left side of my face and ear. I told my doctor that driving must be the cause. The other problem is my right arm which is always my lead arm say in painting my house. But other areas are just delayed. Now I have precancer and cancer on the right side of my face. I have had about 9 basil cancers removed with Moh surgery. Another 4-5 precancers with cryogenic. Now have another 4 cancer spots to be removed and just had 3 precancer spots treated with Carbolic Acid. In addition I have had over 20 moles removed and have another 30-40 to be removed. (Most have been Dysplastic Nevi Atypical) See thats the real secret of how I am losing weight - just cut skin off.
