I retired (after getting diagnosed with incurable cancer). I was a workaholic and never thought I could quit so easily, but after quiting I don't miss work and I'm a lot happier (despite the cancer thing). If you are obsessed with work and in a position to take a few months off, please consider doing this. It may change your perspective.
Prostate cancer. No, I have limited faith in medical science and none whatsoever in alternatives.
Like I said, I'm quite happy and don't cling to life. I'll enjoy whatever time I have left to the max, but there's no need for me to maximize my time on earth (i.e. quality over quantity).
Hell yeah. Agree a lot, and when the fear of losing life is reduced or gone you can go out and do what you want and what needs to be done with your remaining time.
Enjoy your time, relationships, and the beauty of the planet!
