I am child free and 48. Aging is coming across my radar now.
Firstly, I intend to respond to the changes I see happening and treat my body with greater care.
Secondly, I am all set financially and intend to get better there too.
Thirdly, I don't fancy treatment for serious issues. If I got a serious illness, I might choose to check out rather than have nasty treatment that may not work.
Finally, based on three above, I make bloody sure I live the life I want to before it's too late. I do not regret my choices, I have been brave and made decisions (I chose to work in the third sector, giving up a higher salary and then struggling and working extra shifts, BUT with a big tick in the career box that silenced all my questions) - live a life that excites you and satisfies you, and in my case, I accept that it doesn't last forever and decisions then need to be made.
I'm not ready yet tho, haha!
