I think this "nummification" is just part of a bigger "Peter Pan" syndrome in the western world. besides being able to live in your mother's basement and get health care from her until you are 26, now a team of psychologists in Britain are declaring that you really don't become an adult until you are 25.
In medieval Europe, you were an adult by 16... granted you may only have a life span of 35 years so you really couldn't afford to be that unproductive for more than 2/3s of your life. Now with the potential of 100 years, 25 is reasonable as long as you have the means (ie the government) to lay around a gaze at your navel until the age of 25. besides, there aren't any jobs for you anyway.
maybe we could get some diaper manufactures to provide sizes that fit up to 25 year olds so the little dears can stay attached to their video games without bathroom breaks...
How about all the nutrition you could need in one convenient pop tart for breakfast and hot pockets for lunch and dinner, both easily available to "pop into the combination refrigerator/microwave/computer center," again so the game need not be interrupted by the need to feed.
Heck, you can get the latest version of Sym City and live your ideal, perfectly flavored life without ever leaving the sofa in the basement
sorry for the rant.... just had to get it out
