I had thought that I will never say these words. My philosophy is always that if you are young at heart, you are always young. Of course, you need to be healthy too. Nobody says you are young when you need two people's help to get in and out of a car.
Here is the last straw: Check if you can hear this. If you cannot, join the club. You are getting old. This is a high pitched sound that most adults over 30 years of age cannot hear. Kids can, though. Isn't that cool? I mean, the discovery, and not the fact that we cannot hear it. It has always been known that gradual hearing loss (to high frequency sounds) occurs in adults. Someone was clever enough to find uses for it. This is widely used in malls to disperse annoying teenagers gathering around stores, and scaring adults (with buying power) away. They play this (supposedly) annoying sound over the speakers, and drive the kids away.
Now, some kids looked at this and said "Hey, why don't we use it in cell phones as ringtones, and our parents/teachers will not know that we are receiving text msgs or calls". Presto, we have Mosquitotone ring tones. Smart kids.
