It's really up to you. You can put up with some discomfort and difficult side-effects now in the hope of seeing your 90s (and maybe beyond) in good enough health to enjoy them, or stick with milder care now so that you have the energy to make the most of your early 80s, when you *know* you're still fit and mobile.

The important thing is not to let your healthcare team make assumptions based just on your age. This is *your* choice, and if you're absolutely clear (and stubbornly persistent) about what you want, they should follow your wishes as much as medically possible.

(For me, the choice was easier: I was 56 in 2021 with a de-novo stage 4 prostate cancer diagnosis and paraplegia from a tumour compressing my spine. I had a lot of years to lose and my mobility to try to regain, so I told them I wanted to fight like hell, and reminded them at every opportunity: they promised to "throw the kitchen sink at it," and so far it's working.)
