At 50 I gave up booze, got much more careful about my diet, and increased my exercise- initially more cardio and yoga, but switched to more weights, mobility and determined upping of my step count. I lost about a stone and unlike other times in my life when I’ve lost weight, I’ve kept it off.
At 60, my body is thanking me. I’ve got rid of a lot of the tendinitis, joint pain and weaknesses. HRT probably helped too.
Sleep! (No booze, exercise and HRT helped there too).
I’m fussier about my clothes- I declutter regularly and don’t hang onto anything that no longer feels right, or which has given good service but needs retiring. So I do buy new, but carefully. Spend more on individual items but buy fewer, basically.
Personally I’ve gone grey, and really like it. It suits me very well but some people hate greying. I’d rather spend the hair maintenance budget on other things like dental care, the occasional bit of Botox (although I’m not a zealot) and- next month!- getting my varicose and thread veins in my legs fixed. I’m hoping this means I will happily wear shorts if we get a heatwave next year.
Have fun, OP, it’s a good decade, and the 60-70 is supposed to be even better!
