Hello, I'm Greg Jenna and good news, Your Dead to Me is back for a new series. Here we go. Yes, we'll explore Emperor Nero's notorious reign with Professor Marybeard and Patton Oswald. I would not want my daughter having the remote control, not alone an empire. We'll dissect the decadent life of Philippe Duke-Dor-Leon with Tom Allen. I've often tried to pretend I'm an aristocrat and being very quickly knocked down.

And there'll be so much more with comedians like Olga Koch, Mike Mosniak and Rihalina.

I'm excited.

You're dead to me.

Do you think I just have to go for it?

Yeah, just glide off.

Oh, that was some seriously cold water.

I took a dip for a good reason, though, because we're going to find out

if it's possible to boost your immune system.

Because, well, let's be honest, who wants to get sick if you can avoid it? And we are, of course,

in the middle of a viral quodemic this winter and it's putting hospitals under intense pressure.

So we're going to take a look at some of the most common claims about immune boosting,

including cold water, exercise, vitamins and foods that boost good bacteria.

So let's get into it. We're joined by our resident GP, Dr Margaret McCarney. Hello.

Hi there, Jims.
