Welcome to the club and to the forum. I highly recommend retirement, it's the best job I've ever had. I've only been at it for 12 years, it's a tough job but someone's got to do it.
There's lot's of good information on this forum and lot's of folks that can help you with whatever comes up. Have fun and enjoy your new found freedom.
When I was a kid I was going nowhere fast, now I'm an old man I'm going everywhere slow.
