I say, don't keep calm and carry on, take this as an example that life can end any second, just like that, out of nowhere. Live your life enjoying what you do. Most of us don't, which is sad. If you're enjoying life to the fullest, carry on. If you aren't living your life to the fullest, then no, don't just 'carry on'. Life is fragile, and this should be a reminder. I for one know, I shouldn't 'carry on'. I need to improve my life.
Make the most out of your precious time.
Good read btw!
