Misplacing stuff is frustrating.  More frustrating is completely forgetting an event that was on your calendar.  And the more I forget things, more I jokingly say, “I must be getting older.”  But it might just be true.  It turns out that we reach our peak at 22 and by age 27 we may start having reduced mental abilities. That means that even earlier we need to start doing everything we can to challenge our minds and stay sharp.  It also means we all have a really good excuse for not being able to find the keys.
