Experience is irreproducible. It depends on too many factors, we even don't know the full list of them, and some of them change irreversibly with time passing. You will not be 10 years old anymore. It is not a good reason for a depression, you can experience world now like you couldn't being a 10 year old boy.
Actually one of the absolute best things about having kids, that is not reproducible for no-child lifestyles, is seeing everything for the first time through their eyes.
All the other stuff people say about parenting can be reproduced via service or volunteering or something else. But that experience absolutely is unique.
Magic is real. The world is wild and exciting, and it's all there for that kid. It's amazing to watch and be a part of.
So, while you can never go back to being at 10 year old boy, you absolutely can get a taste of what that's like via adoption or having your own. In my opinion, that is.
