My maternal grandparents are in their mid 90s and as recently as right before the pandemic they were both entirely independent, so it's not impossible.
Part of their secret seems to be living on the fourth floor without an elevator for seventy plus years and going out on a daily basis.
I can't hope to live this long due to years of leading a sedentary lifestyle, but I invested in an apartment that's more than 64 steps above ground and on top of that has two levels, so every time need something from the kitchen I have to go down and up again to where I have my desk.
