Great comments here! This is something I unfortunately think about a lot, because barring an accident I do in fact know how I'm going to die. I don't know when, and it's hopefully not for a lot of years, but the clock is ticking and I'm quite aware of that now. I, too, lived under the illusion that I will live forever. But that isn't true and I'm glad to know that now rather than realize it when I have too little time left. When is the time to do that thing you always wanted to do? The time is now. It's now. Not next year. Not 'some day.' It's now. When is the time to tell that person the thing you've always been wanting to tell them? It's now. Do it now. This awareness has made me brave, and my quality of life is rocketing upwards right now because of it. I think I've never been more alive.
