Guys, thanks for all the input, much appreciated.
For some reason, a bit of a strange sensation of guilt comes and goes, but not sure why. Looking it up on the net, seems to be a normal response when taking early retirement.
I think time will tell what I plan to do. Definitely taking the summer off. Was working steady nights for the past eight years, so this will give me a chance to get back to a regular sleep pattern. Biking and some weight training is something I also want to get back into - tennis would be nice too, but need to find a partner for that.
Eventually would like to get back into sketching and portrait painting, something I've ignored pretty much ever since working full time. Here's a self-portrait from my college days...
regards,
Jack
