The truth is we are all on a one way trip, and we don't know when we will be asked to get off. Stop worrying about it and start living before it is too late. Me, I have almost died twice: once in a boating accident, and once in a really bad car smash. Not sure if I will make a third time (three strikes and you're out!). It gives you a total new perspective on life, and I wish most other people could experience it (without the pain of the accidents). It is hard to explain, but you loose all interest in the ego and material things and become at one with the world and gain a deep understanding.
I don't waste time, I get out and do things I want to do - I kinda live my bucket list. Make a list of the things you real want to do and then do them one by one and tick them off as you go. Hopefully, you will have a enough time to complete the list, but many don't but a least they lived a life.
How long have your or I got left? You can try here - death clock to see how long you have got left to live.

Me, according to the clock, I have got until Sunday, January 31, 2044 to life which makes me about 84, and I am going to make every second count.
So turn off your computer, write a bucket list and get out and live your dreams today before it is too late - which could be 90 minutes from now or 90 days, 90 months or 90 years.
