If prices of plastic and gas keep going up, we'll need to switch to electric cars. As for toys, I think they'll be out of the picture too, since they will become too expensive as well. I predict that will be collecting food in the future because:
1) we already buy it
2) you can buy it either loose or mint in box (that's a lot of cereal boxes for you mr. 5h4rk :lol:)
3) you can still play with it although it is socially not accepted in most civilizations, but the good news: you can still play with it
4) Unless you're a mint in box collector of course, you can eat it, this way you get to enjoy what you collect.
5) And you can display it.
