I will try to get to blogging here, but for now, have a look at my sculpture website -- this is something I began doing after semi-retiring in 2001 at age 42 and have been really glad to fill my days and years with this rewarding activity. If you're wondering what to do after early retirement, here is one example! Bob Clyatt Sculpture. I'm also a pretty reliable updater on Facebook where you can follow me on Bob Clyatt Sculpture.
Good luck with your semi-retirement planning!
