Is life better when you are younger or older?

Personally i think younger. You may not have as much spare time to do the fun things that (mostly) make up how "fun" your life is(although that's relative for everyone) but as a younger person you are fitter and able to do more in the spare time you do have. As an old person you are limited in your activities because your body isn't capable of doing so. Imagine your grandma in a rollercoaster. That wouldn't end well, would it?
