Congratulations Skid! You deserve it after working all these years. As far as your health, you shall overcome that. Just like my dad, he retired 9 years ago and he said it is one of his best decision in life. He battled prostrate cancer right after retirement and now is enjoying retirement life to the fullest. He goes back home to the Phillipines every year for 2 months. I get jealous time to time.
Again, enjoy your golden years.
