So a baby's born relatively sterile and then is consequently sort of colonized by microbes, healthy, good microbes that then train and educate the immune system.

So this is probably one of the biggest inputs we have to the sort of trajectory our immune system has throughout life.

But then I think we can continually nurture those microbes by the environments we go into, the food we eat, the things we do that we know from the latest research, for example, gut microbiome research, which has exploded in the last 10 years, to try and continually nurture

that good immune health.

I mean, there's studies looking at frequency of cold and flu viruses in winter when you use like a dietary fiber intervention because you're improving the microbes in the gut.

They're improving how the immune cells are functioning in the gut and then they're recirculating around the body and providing better defense to infection.

Potentially, yes.

Mm-hmm.

Yes, exactly.

And I think it's like not getting too worried about the one night of bad sleep that you might have heard can like deplete, you know, your ability to respond to infections.

It's more thinking about in the UK, the lifespan is around 80, depending on where you live.

Yeah.

think about the life course and not just focusing on the one bad meal you had or the one, you know, bad night's sleep.

I think we have to, to me, we've already had a longevity revolution and everyone keeps speaking about it.

You know, we have people like Brian Johnson and these people who are like pushing the boundaries of lifespan.

But, you know, it wasn't that long ago that people would barely live beyond 50.

That's really, really close in our evolutionary history.

So we've already kind of gained all this extra time.

But then I don't know about you, but everyone has not enough time.

Like whenever I want to see friends or do things, we all feel like this time purr.
