I am only 23, so I still have decades to really worry about retirement. Sometimes you will see a commercial making retirement look like an amazing thing with new adventures etc. but when you observe people who are actually retired, they look bored out of their minds and they need to find hobbies to keep them occupied.
The truth is, retirement is fairly new. It was only one-hundred or one-hundred and twenty-five years ago when we started seeing the retirement we have today. Back then, even the able bodied elderly had to pitch in and work. I think retirement is overrated unless you have a really boring career that pays good, then I'd understand.
