Congrats. IMHO, retirement is one of the biggest adjustments in life.
It may not be bigger or more important in general than getting married or having children, but I think it's a bigger lifestyle change and as a result harder to adapt to. I know it took me a while and I'd be shocked it that wasn't true for the majority of retirees. The end result is worth the difficulties of adjustment though!! Look forward to you joining us here in TV!
