Yes and I've heard a little advice about keeping healthy on the radio and telly (VERY LITTLE) . Of course people should stop smoking.
We also should bring up our immune systems. I Eat fresh lemons and garlic/water [blended] include the skins and pith because they have large amounts of Vit C, more than the juice!! Oh and always eat fruit on an empty stomach because we get the full benefits of the vitamins etc. from them.
Mind you seeing the queues around effing Mcdo's before it closed I wonder why anyone bothers to suggest anything healthy to people, they don't care for themselves. Great for the NHS.
