One thing for us old folks to watch out for is tattoos and diabetes. The color has to be refreshed in a tattoo every couple of years because it fades so if you come down with diabetes as you get older, it is a bad thing. Diabetics are not supposed to have tattoos. Poor healing and all that junk.
They do fade. When my DH was in the Navy he got a tattoo of a red anchor by Lyle Tuttle (famous tattoo artist back in the day in San Francisco). Well, several decades (heck, several score) later he wants to get it freshened up a bit. Nope. No legitimate tattoo artist will touch it...it would be like defacing a masterpiece. So DH is stuck with a [COLOR=EE82EE]pink[/COLOR] anchor....
Many stories about tatts. I have one friend who flew choppers in Nam. Saw a lot of horrific things. He coped with the pain by getting tattoos, full arms both sides, then chest and back. You wouldn't know it unless he wore a T-shirt. The guy is decent as the day is long.
DH loves getting tattoos. I have one, but kept it hidden from the family until after Mom had passed. She, being the proper Victorian that she was, truly would've disinherited me. The first time DH was helping me do yardwork at Mom's house (I put in her veggie garden every year) she came out and just stared at the tatts. She went inside and soon Dad came out. Then I heard the conversation:
"Well, he's a sailor, Dear. That's what they do...."
