Musings from the recent news about Malaysian Airlines plane crash

I am reading this news earlier and I just found myself in tears. http://edition.cnn.com/2014/03/08/world/asia/malaysia-airlines-plane-missing/ I am left with the conclusion in mind that man cannot tell up to when he’ll gonna live. It’s all in the Almighty’s hands. How can I maximize the entire time of existence with His help and mercy?
