That one white hair strand on your head is a potent reminder for all of us [COMPACTIDEA]

All/most of us have it. It shines brightly and we try to hide it [we've all been told not to chop it or else all our hair would go white]. One can have a few such strands even in one's early 20s. Annoyance aside, this white strand serves as a reminder to us all about our eventual fate - old age, frail body, reduced mental abilities, and eventually death and conversion of what we used to be into dust and lifeless molecules. Perhaps looking daily at this one white strand makes us be a better man.
