Sir David Attenborough

In a 2013 interview on ‘The Jonathan Ross Show’, TV biologist Sir David Attenborough, 96, opened up about the medical conditions he lives with, specially the cardiac issues that at some point threatened his career.

He said: "I had a funny five minutes. No more than that. I had to go to Australia and the insurance said they wouldn’t insure me to go on a long flight unless I had something to monitor my heart to make sure it didn’t do funny things. So, they give you this thing, it’s called a pacemaker. And all it does, if your heart suddenly decides it’s going to skip a beat or something, it kicks in. And if it doesn’t, it doesn’t. And I don’t think it has."
