Getting old sucks. Old men once had hair, teeth, and a dick that worked. Now they don't. Now they wear a hat, wear dentures, and take viagra.
When they were young, old men used to be strong. Now they can barely walk up the stairs.
Younger guys can eat tasty bad food, drink a lot of booze and party all night. When they get old they can have clogged arteries, a bad liver, and have to go to sleep at 10 o'clock.
It's no fun getting old. But, considering the alternative, being old is better than being dead. Being old may not be fun but being dead is REALLY not fun. The good news about being old is that, when you get old, you acquire wisdom. And peace. And, if you're a guy, you can still look at, and appreciate, pretty women (no, I am not promoting leering or ogling, just looking).
Getting old sucks. Is it worth it? Yes! In spite of the ailments and frailments of getting old - life gets simpler - and often better.
