You do realize that everyone spends all day every day viewing 3D content. Real life is in 3D.
If young people can handle 3D longer than older, than the one thing that is different from Real life in 3D TV, the focus
distance, is not the problem. Us old guys can only focus at one distance anyway. The only thing left then to cause problems, is
mistakes in the photography. Just because they are doing it wrong now does not mean they won't learn to do it right in the future.

The saving feature of 3D TV is that you can turn off the 3D, take off the glasses and watch it in 2D.

So far, every new technology for entertainment has suffered an avalanche of haters and dire predictions of its demise at its
inception. This was true of the cassette tape when it replaced real to real and 8 track, CDs when they replaced LPs, and most
recently HTDV.
I personally think that 3D TV will be great for video games.
