If you can keep living, you’ll probably have a chance to live even longer. Medical technology continues to advance at a rapid pace. Don’t burn yourself out early, thinking that life is short anyway.
It is relatively short, but it’s getting longer. The average lifespan used to be 35-years. That wasn’t that long ago (less than 200 hundred years ago). Now it’s approximately 80-years and continuing to rise.
Take care of yourself and look forward to better days ahead.
