, I looked up H2O2 generators. They cost a lot less than $8000. On a different note, travelling is a great thing to do when you retire. $$$$$ it can be expensive - obviously - but it's something to do while your body can still do it. Your body does get older, and sometimes it's the idiot doctors, and sometimes it's just old age.
SP, thinking about writing????? Cool. I've self-published on Lulu and on Kindle (Amazon) for free. The last time I tried to use Lulu, the wanted money. That was a few years ago. Maybe they'll do it for free again. If you have any questions, I don't know everything, but I've made a lot of mistakes. Soo if you run into questions, I'll try to help if you want. You mentioned photos and drawings . . . I know you have to go to work, and yes, that does get in the way of creating.
Me - I've finished to-do list number three, and I'm on #4. And of course, tax time is just around the corner.
Sigh! I've been doing physical therapy because my shoulder is stiff, and I can only lift my arm halfway. It improved my mobility in moving my arm towards my middle (as in hugging.), but lifting my arm is no better, and i think it may be getting worse. Again, sigh!

Ok, this me signing off.
