Hello and welcome to Health Check from the BBC with me, Claudia Hammond.
Today, why is it that we remember very little, if anything, about being a baby?
How it's worth trying to resuscitate someone who's had a cardiac arrest
while you wait for medical assistance.
And I'm joined for the whole show by BBC health reporter Smita Mundasad.
Now, you're going to show us actually later on how CPR is done more.
Someone's going to refresh my memory of how it's done.
Fair enough.
And what else do you have for us?
We're also going to be looking at a transplant of a pig liver into a human.
This is extraordinary.
Now, imagine that you know you have an illness which could kill you,
and you're taking part in a trial of an experimental treatment which might be your only hope for survival.
But one day you hear that cuts to research funding are now planned.
This is the situation Marty Ryswig finds himself in.
He lives in the United States, where the National Institutes of Health,
the world's largest public funder of biomedical research,
has announced substantial cuts to research grants under the new administration.
