Death of high school friend

I am reminded how short life is. I moved away from my high school town after graduation and pretty must lost contact with everyone. We did not have social media back then. Then an old friend linked with me on facebook a coule years ago. I found out a guy I used to run cross-country with had died. Not only did he die early, but I hear reports of others who died before 60 of natural causes. Wìth the average life span of 78.7 years in the US, I would expect most of my high school peers to ive into their 80s. My logic would be the number of deaths from car accidents,etc. For example, our class president died the first summer after graduation from drinking nd crashing his car.

My take away ould be to number my days and apply them to wisdom (Psalm 18). I have some thinking and processing to do on ho to better invest my time.
