Hello Brummie. Yeah the big 40.
In my case, it wasn't as bad as I thought it was going to be.
25 was tough for me. That's when I figured out I was for sure no longer a teenager, and I recall, still being in the org. that a lot of the youger ones in the cong. subconciously or consciously treating me like an " older person " LOL.
40 was actually the best birthday ever for me. My wife and I had been out for a few years, and she arranged a surprise birthday party for me, with friends we have acquired sine we left. And now that I have a much better outlook on life, the successive years, are a lot more enjoyable than the previous.
Cheers !
