The more I think about MS the more I realise that we should be focusing as much effort as possible on prevention. 
The modifiable risk factors that have been identified should be well known to you by now:
1. Vitamin D
2. Smoking
3. Epstein Barr virus

Addressing factors 1 and 2 requires a change in behavior. However as with all public heath issues it takes a lot to get people to change their behavior. One of the methods that has recently been proposed is “nudge”. 

A detailed account of the “nudge theory” can be obtained from the following book: 

“Nudge: Improving Decisions about Health, Wealth, and Happiness” by Richard Thaler and Cass Sunstein.

Unfortunately it looks like it’s going to take more than a “nudge” to get people to change their habits to prevent MS in the UK. The House of Lords Science and Technology Sub-Committee  recently issued a report on behavioral change policy that finds “nudges” and similar behavior interventions ineffective in influencing behavioral changes when used in isolation.
So we are going to need your help on taking basic prevention strategies forward! I am particularly concerned with the trend in young girls with regard to smoking (see previous posts). Any suggestions would be much appreciated.
