What this basically says, being more active and less sedentary significantly reduces your risk of death.

The obvious.

This is the Department of Obvious, isn't it, really?

But actually, what it means is right now, you've got to get your New Year's resolution in place and get off your couch, stop watching TV and start doing some activity.

And that's what you need to start for 2020.

Well, I actually think you two are getting there, aren't you?

No, I don't think we are.

Well, it depends how old you are, doesn't it?

Isn't 50 the new 40?

Well, I think it's interesting, and we've been looking into this, whether the problem is now is that in selecting research, we're starting to skew to these new type of issues like all metrics because they get you this instant hit in the news, the blogs, the Twittersphere.

and so editors are starting to choose this more often and we're actually taking a bit of a look at this at the moment so we'll come back to you in the future but i think it may be skewing the choice of articles so it becomes a self-fulfilling prophecy that you're more likely to see this stuff because actually it's more likely to get this high alt metric that might not actually bear out though in the citation so we don't understand the impact i think they are correlated

yeah but whether the impact in future decisions about it changes in healthcare and guidelines be interesting to see because there are not many of what i consider the important systematic reviews or randomized control trials in this top 100 because there's lots of observational studies in there perhaps it also relates to as science becomes increasingly open to the public what topics the public can easily identify with and tweet and engage with and blog about themselves as well

Now, actually, I have to say it was... The first thing I need to say, what an amazing conference.

The Prevented Overdiagnosis Conference is one of the most...

thoughtful events that I go to or I've ever been to.

It makes me think and I come away with so many issues and thoughts about what we're doing in healthcare, what we're trying to achieve.

But before that, yes, I was in Sydney.

The smoke was horrendous.

And there was a report in the newspaper said that if you're outside today, it's equivalent of smoking 37 cigarettes a day.

And it must have been like what it was like in the 50s before the Clean Air Act.
