Two passengers on the bus.
One was clearly younger than the other. I could tell from their skin.
The younger one appeared in her twenties. Smooth, clear skin with just a light touch of make-up. She would easily be considered pretty, if not beautiful.
The other woman was much, much older. Hair dyed brown but not quite covering all that silver-grey. Her skin tanned and wrinkled. Was she considered pretty or beautiful when younger?
And it occurred to me:
Some people might be born beautiful or handsome. Those who are not can always achieve some measure of beauty through cosmetics and science. But no matter what, the passing of time ultimately robs skin and muscle of the potential to appear beautiful.
Our minds are a different matter though.
The possibility always exists that minds will become more beautiful with age.
