Smoking causes cancer. Nobody disputes that fact and there are regular campaigns about it. Obesity also causes cancer. No one seems to actually dispute that fact either, but it’s not the subject of so much campaigning. It really should be. These days, obesity is more socially acceptable than smoking in lots of ways.
I’m obese, I know it increases my chance of getting cancer. I don’t get angry with cancer charities pointing that out in campaigns.
