Sticking to the RR for years

I just started the RR a few weeks ago and I really like it, but today during my workout I was wondering if it is sth that I'd be able to stick for years.

My primary goal with strength training is longevitiy, health and mobility (and of course doing cool stuff like handstands) and the thought just hit me that so I'll have to train like this for 50 years? :D

So I was thinking about starting a discussion about how long have you been doing the RR (or sth similar), can you stick to training for years - and I mean really long periods like 10-20 years.

I am curious if training for longevitiy really works if you start it in your 20s-30s. Because life always happens and I know how easy is just to stop "living healthy".

For me eg. it was always hard do the same thing for a really long time (except cycling, I did it for 10 years, I am on a break now, but I hope I'll get back on it when my kid will be bigger and I'll have ridiculous amount of time again :D ) so I' be happy to here about fellows who successfully doing bodyweight training for life - and not because that's your job.
