There is very famous quote:

Live every day like it is your last day

Maybe because we do not know how much time we have we do not really appreciate it and think that it is us, we are hte main character of life and anyone else but not us.

When I was a child I thought that I am different and maybe have really blue coloured blood because I didnot feel like I am hte same like others. But you can imagine my disappointment when I found that I have normal red blood and also get a viral infection like any other person.

I am sorry to hear about the loses of your friends, those moments we are waking up and start to think about our own time. Glad that you Joan, reminded again how precious our life is.
