Congrats! All I heard from my brother is that he should've done it sooner. I found out he was right! No stress, no deadlines to meet, no weekly boring meetings, etc. I get calls from my former co-workers a couple times a month and a quarterly visit to help them out, especially after the one that replaced me quit. I was asked if I would like to work as a part-time contractor and said no thank you, it'll mess up my IRA to Roth conversion plan... but would come in to help for a day here and there, if needed.
Nice to do things at your leisure and not run around on weekends trying to get things done, along with taking a break day here and there, to do nothing but grab a drink, sit on the deck and listen to talk radio.
As for Medicare, I went with N plan instead of G. It was my understanding that with F phased out, G would become the new "F" where most people would go and where others with Advantage plans would try to get on, therefore yearly increases would be larger than N. N requires a co-pay of $20/visit, cheaper monthly (i.e. 120 vs 88). That works out, unless you have a lot of doctor visits.
