But (I must add), I'm off to the gym to lift some weights! We can't give up!

Just so. I don't even drink much. When they asked me in the ER about alcohol consumption, I said "A couple of glasses of wine or cider."

"A couple a day?"

"No, a couple a month."

The thing is, there's no self-denial in any of this for me. I live in an urban neighbourhood with hundreds of shops and restaurants near me, so of course I walk a lot. I don't enjoy alcohol much, so I have an occasional drink mainly just to be social. I went off meat after a stomach flu in 1997, and couldn't manage to get back to eating it. And I've always hated the smell of tobacco, so I've never tried it. We cook most of our meals from scratch because of all the food shops near us (plus it's cheaper and tastes better), but it's still fun to junk out every Friday for "takeout night." (Being healthy doesn't mean you have to be perfect. 🙂)

Did healthy living prevent my stage 4 prostate cancer? Of course not. Life doesn't work that way.

But it *did* put me in a better position to fight it. I came in at the start strong enough to fight my way back from the wheelchair to walking over two tough years while also dealing with the side-effects of ADT, Erleada, and two rounds of radiation. This last year I've been reaping the benefits, and have gotten used to the ADT to the point it barely bothers me.

That — not a miracle cure or magic protection against cancer — is the real benefit of a healthy lifestyle.

I’m sorry I haven’t reread your post completely but my question now is this…
My husband starts chemotherapy on Monday are you aware of applying a cold compress to the scalp while chemo being induced have saved the hair?
