It was a pleasure reading this, something to give hope for people who think or believe that growing old means that the mind and brain start slowly degrading.

The way I see it, that's only because we stop imposing challenges on ourselves, we corner ourselves in the hellish domain we know as "the safe zone" and start rotting when we should be seeking challenges, pushing and punishing ourselves into more situations for our minds to relish in and adapt to, however suffocating, exhausting and complicated they may be.
