As an obsolete being, I'll say that my 30s were great, much better than my 20s

Life begins at 30 so I heard.

I'm 60. I didn't notice things starting to suck until about age 45. So, you have that to look forward to.

But, also, I'm happy enough to get older, because the only alternative is worse, IMO. I still complain about getting older, don't deny me that pleasure, but I don't really mean it.

When I was nearly 30, I went through my first major depression. And, I got through it. What I learned is that I could get through it, that was helpful for my second major depression.

What about age 30 means things are over?
