Outside of hijacking this thread from a bass repellant discussion into one of melanoma, I hope that some of you may realize the value it has to the younger readers on this forum instead of how not using it puts more fish in the boat. :
My father in law (of 12 years) is a dermatalogical surgeon, and the subject has been repeatedly discussed over the years. He is the primary source of my research. Contrary to your ill-informed beliefs....All skin types are diagnosed with skin cancer, and whether or not you get sunburned is not a determining factor of being at risk. Yes, some skin types are more prone than others, but NONE are excluded. I "assumed" since your father used sunscreen, you would has a similar skin type (which apparently I'm wrong), but like I said...All skin types are prone to melanoma caused by over exposure to the sun.
FYI, my father had skin cancer removed from his nose 20 years ago at age 45 and he too has contributed to my "research" over the years.
In an effort to contribute to the original discussion, I used sunscreen at all 17 fishing tournaments last year, finished 4th in points in our club (out of 40+ teams), and won our classic. All with the help of sunscreen, and I didn't wash my hands after I applied it. Bull Frog seemed to be the secret attractant.
