Goodbye.

On the physical capacity scores, you tend to see pretty stable trends for all age groups.

So this is true for people in their teens and 20s.

It's true for people in their 50s and 60s.

And if anything, we actually see a slight improvement in the answers people are giving about specific physical health functioning over that same period.

Whereas if we look at people's responses to questions about mental health, which refers to their worries, anxiety, depression, the extent to which their mood and mindset is sort of a struggle for them.

This is where we see this marked decline for young people in particular.

What we see is that the physical health score has had very little impact on this decline in self-reported general health, whereas the mental health scores, the responses to those questions, track very, very closely with what people are saying on their overall health questions.

If we're talking about what's changed over recent years, during which we've seen this fall in healthy life expectancy, people in their 60s and above are not the answer.

They're actually doing reasonably well, if anything, slightly improving.

Yeah, look, I'm not a huge fan of it.

I don't think there is a good reason for us in a country like the UK where we have all this data to try to lump everything together into this one statistic that has these flaws.

Thanks for having me as always, David.

Yes.

So we're talking here like the 1800s and a lot of the 1900s.
