Thanks for bringing this up, Larry. I need to go in and get a bunch of new "precancerous" spots norched off. Last summer's and this year's. They weren't there before. My lips probably need the same treatment yours are getting. they feel tender nearly all the time now. Even the best SPF 100 waterproof sunscreen that money can buy is only good for less than 2 hours while surfing or swimming. I've been joking that I am the "sheik of the soggy sands" here, since I've been wearing a flats cap with a sun veil in the back, and always long sleeves. I always wear my hood and gloves when surfing, even on hot days when the water is in the higher temp ranges. I'd rather parboil than fry. I am now in the very highest risk category for skin cancer. I have all the qualifications. Fair skinned, and I freckle easily. My parents let me get severely sunburned on a vacation to the Russian River when I was only 4 years old. I had huge second degree sunburn blisters on my shoulders. The doctor at the clinic in Guerneville (sp?) told my parents that it was easily the worst case of sunburn he'd ever seen. He even gave 'em a bit of a scolding about it. Then, after we moved to Honolulu when I was 16, I was taking tetracycline (broad spectrum antibiotic) regularly for nearly 3 years. That was prescribed by the dermatologist I went to for my bad acne. One problem with that, is it makes one much more susceptible to sunburn, and I was a surfer and beach goer. The sunscreens we had back then weren't all that effective, but we thought they were working, so my surfing buddies and school chums and I stayed out in the sun much longer than we should have. My lips got burned all the time. My entire face, too. Zinc oxide would easily get smeared off, and its messiness deterred us from using it. I started using a sunscreen called PreSun. I think it was nearly worthless, due to the ineffective ingredients in it at the time (late 60's and the 70's) and using it did more harm than good, since we thought it was working. I'll have to pay cash out of my own pocket for this, on the "easy payment plan" as I haven't been able to find any medical insurance cheap enough that I can afford the monthly payments. The cheapest quotations I've been given are over $350/month. My one visit to the dermatology clinic to get a "cutaneous horn" removed from my face (Office visit totaled 15 minutes, procedure took about a minute, total) cost me over $500 by the time the lab fee kicked in. If I only have to do that a couple of times a year, I'm still miles ahead of making insurance payments. So you young folks listen to Larry and me. We ain't blowin' hot air here. Maybe you can avoid this type of thing in later years. I had a good surf session this evening, from 5:45 pm until about 7pm. I slathered my face with SPF 45 about a half hour before I went out. It was overcast and drizzling, but I still needed it.
