Well, we just aren't going to do most of those. For 1, I'm a bikini girl. Not going to wear long sleeves and long pants on the boat or by the pool. For 2, not going to stay indoors from 10 to 5 or whatever. For 3, we do have a top always up on whatever boat or bridge so do that pretty well. For 4, we use sunscreen and neither of us has been burned at all in the last 17+ years. Not since the winter of 2000. For 5, we do wear sunglasses. Hubby didn't till I "splained" the rules and now he has bunches of them. For 6, we're not going to say this is a bad UV day and we can't go out.
We've had no one burned on our boat or in our pool area. We load on the sunscreen as most don't put nearly the quantity the tests are based on. Funny, the younger people have no issues. Now, 60+/- year old couple who have been on the water their entire lives said they'd never used it. We said, "well, that's about to change." I would classify them both as high risk.
We've started the two 3 year olds on sunscreen from the outset. It comes natural to them to put it on. You mention the pool or boat and they immediately come to you and say put it on them. Just like PFD's which they love (I did find them cute ones) but they associate with the fun of boating.
I don't want to fear the sun but just be sensible. Hubby and I went on a walk in the dead of winter, a couple of months after we met, and he got burned and I felt so guilty that I hadn't noticed him burning or done anything. That was it. Never again.
We need to protect those we love, including our friends.
Oh, we only use SPF 50 or so. The chemicals in some of the higher ones have their own negatives and issues.
And thanks to all you older guys for sharing. We do listen on topics like sun and some of you have experienced what we want to avoid. We value the wisdom and experience.
One last thing. If your dermatologist hasn't checked every inch of your body, they haven't done what they should. Have your spouse or someone do that as well. There are areas you can't see or don't notice. Anything that doesn't look right needs to be checked. If you've got no one to check for you, at least get mirrors and do it.
