Going to extremes to give back

A former RAF police dog handler from Lincoln who waited 20 months for a heart transplant, says he now wants to help the people who helped him.

Alex Smith, who's a father of two, appeared on Calendar last month whilst waiting for a heart, and finally got the call he'd been waiting for.

He's so grateful he now wants to go to extreme lengths to give something back - as Kate Hemingway reports.
