Well I retired 8 years ago and I do not know how I found time to work before. I fish a lot, hunt as often as I can, work some around a farm my sons inherited, watch my 6 grandchildren play travel hockey all over the east coast, high school and travel baseball, football and and travel/collegiate lacrosse. We have a new grandchild that is 1 1/2 years old now so I do not see us running out of grandchildren trips over the next 15 years.
If you can afford it I highly recommend retirement if you get out and do things. If you sit in the house and watch TV then it is not going to be a lot of fun.
