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.

I'll be finding out why first aid knowledge is so poor in the UK and asking what can be done about it.

jab to protect against shingles, a late complication of chicken pox that causes a nasty

crusting rash and which can leave those affected in pain for months

and sometimes years afterwards. But there's another vaccine that protects against chicken pox

and which could be given to children to stop them catching the virus in the first place. So why has

the Department of Health opted for a jab that prevents a late complication of chickenpox,

rather than the disease itself.

Adam Finn is Professor of Pediatrics at the University of Bristol.

Chickenpox is caused by a virus, which once you've got it, you keep it in your nerves for the rest of your life,

but you keep it under control with your immune system.

As you get older, your
