I'm a sucker for turquoise sea, white beaches and palm trees. I've been to the tropics every year since I could afford it. It's the perfect place to unwind. I can chill out, read, do a bit of yoga.

I'm a sucker for a packet of biscuits. I can eat a whole pack in 10 minutes.
If you're playing a poker game and you look around the table and and can't tell who the sucker is, it's you.
