Britain has had a big influence in Kenya.

What are they going to make of this?

Well, Britain was a former colonial power, but Britain's influence over East Africa has been waning over the years.

And what we have seen right now is a lot of countries in East Africa broadening their relationship and ties with other countries.

They've become very close allies.

Thank you very much.

What is it that you'll be offering different that perhaps then they will generate that excitement?

But I think if you talk to people in Dar es Salaam, in Kampala and in Kenya, the idea is really just to broaden its engagement beyond its traditional partners.

Want to slow the pace of ageing?

Don't fancy exercising or improving your diet?

Well, why not try a bit of culture?

New research suggests that participation in the arts is not just good for your soul, but actually slows down your body's biological clock.

The lead researcher is Daisy Fancourt, who's Professor of Psychobiology and Epidemiology at University College London.

She spoke to my colleague Nick Robinson.

We've been looking at a particular way of measuring biological ageing called epigenetic clocks.

So essentially, we're all born with our set of DNA, but our lifestyles can decide which parts of our DNA get read out.

So a bit like a recipe book, the recipes are there when it's printed, but we only choose to make some of them.

And we've been looking at a process called DNA methylation, which is when a molecule called methyl attaches to our DNA, making it hard to read out, a bit like sticky pages in that recipe book.

And as we get older, there are particular patterns of DNA methylation that tend to occur.
