I think you are looking at this the wrong way. I turned 50 recently. I have ADHD and I was fairly immature for a long time.

I finally understand so much about life, I genuinely am helping a lot of people and to be honest, want to continue living and enjoying life.

There are so many books to read, experiences to have.

Yet I can feel that my body is no longer how it used to be.

If there was something that could bring back to clock, 5-10 extra years. Totally worth it.
