Fitness didn't come true with the Wii. Better be prepared to still go outside and have a life. Your body will produce vitamins as your reward.
Eyestrain is subjective, and this is far from an optometrist's prescription to treat any disease or disorder. Doctors recommend tooth brushes, but which is THE ONE TRUE toothbrush?
Psychology is not hard science. This technology can either harm or help, with no guarantee of either. Use as directed.
> Better be prepared to still go outside and have a life. Your body will produce vitamins as your reward.
Many people don't have good fitness options outside a controlled environment, for a variety of reasons.

No, it's measurable externally!
> but which is THE ONE TRUE toothbrush?
Dentists generally don't give a shit about brands, but ask 20 what the right toothbrush to get if budget is not a factor and they'll all quickly converge on one answer that has a fair sum of science backing it.
The question is 'why'? There's no denying playing a Wii game involved burning calories so the only explanation is that people stopped playing it.
So the question is really about whether or not people will do the same with VR and currently the majority of users seem to think otherwise.
Personal note. I had a Wii and never used it. I bought a Vive 6 weeks ago and have used it every day.
