Should obese people be required to buy two seats when flying?

What annoys me is when you see fat people driving mini electric scooters that are meant to be used by disabled people. I mean, I know it's hard for obese people to move; But when these people have to use a scooter to get round then surely they must realise that it's a serious problem and it's not healthy. I think the thought that I couldn't walk around a few shops because of my weight or be able to sit in a single seat on an aeroplane would make me want to do something about immediately. I know that's easier said than done though.

Britain is officially the third most obese nation on the planet (with 23% of people classed as obese) and I seem to be noticing this more and more each day. It's a rather depressing thought that we are getting that way *sad face*.

What are the first two? I'd guess it the USA and Mexico.
