People in their late 30's and beyond: When you reached your late 30's or 40's, did you start re-evaluating your life, i.e. happiness, career, relationship, housing situation?

I am 45 and recently was off work for about a month for surgery. The time off made me start reflecting on my job, if I’m happy with it, if not, what else could I do for a living, would I change careers at this stage, if it required extensive education. My relationships, my housing situation (will I ever move? will I ever own a house?).

I want to know if this happened to other Jellies upon reaching late 30’s and beyond?
