Question ideas

For my question I want it be about how a sedentary life has become the norm and how we can use social media to encourage people to become active.

Kat suggested this question, however I don't think it fully fits with what I want to write about. It seems to be aimed more towards social media being a massive influence, however I want to write more about people becoming less active and how a social media campaign can influence people.

"How does social media influence young people and how can we use it to encourage them to be more active?"

I decided to think more after/while I wrote my dissertation because I just didn't know how to work it properly. But in the end I decided that my final question is going to be:

How had a sedentary lifestyle become the norm, and how can we use technology to encourage people to become more active?
