The web making the world a healthier place?

The Internet is becoming a bigger part of the average persons everyday life, and with many realizing its worth in terms of personal health the world wide web is becoming a large influence on how people learn sports, activities and skills and how people monitor their progression. The internet is completely full of videos or websites that have to do with getting in shape "get a six pack in 6 weeks" ads seem to be every where. Personal I have gained some help on skills for freestyle skiing, just from viewing videos on youtube and forums and posts on how to do certain tricks. http://www.newschoolers.com/ns/forums/readthread/thread_id/677984/ this is an example of this. Just by watching tons of videos you can help your muscle memory learn movements while your dreaming and certain skills can be learned quicker. Also there is the more direct approach to using the internet to get in shape and learn movements. People interested in losing weight can watch work out videos and imitate them right in their own home for example. http://www.youtube.com/watch?v=b_HWEoGoxgI Another way the internet can help is with contest like http://healthynewyear.challenge.gov/ this promotes people to show how using technology to better there life and fitness. I made my video about how I use the TEVO system of using a camera and TV with a delay to show my dives and improve them. http://www.youtube.com/watch?v=oBqwFXQVOOE&context=C31c957cADOEgsToPDskL9cZL4etmUZMIaB5juWOCB
