Here's approximately how many months I have left, based on data collected about life expectancy for my a/s/l.

Here is one of my favorite quotes I first read in one of my favorite books of all time, A Short History Of Nearly Everything by Bill Bryson. It was first described by John McPhee. He explains that if you outstretched your arms and imagined that the whole of earth's history so far was all encompassed within that span,
“All of complex life is in one hand, “and in a single stroke with a medium-grained nail file you could eradicate human history.”
Our lifespans are infinitesimally small.
It's always a good thing to keep perspective.
