The writer and TV presenter Simon Reeve likes travelling around the world. He's already travelled along the Equator and the Tropic of Capricorn, and recently he completed a third epic trip in the Tropics - this time along the Tropic of Cancer.
The Tropic of Cancer marks the Northern border of the Tropics region - a region which takes in half the surface of the planet and almost two thirds of the world's population.
The Tropics are home to some of the world's most beautiful landscapes, but also to a huge array of human experience - from the positive through to conflict, poverty, and the effects of climate change.
Simon's trip took in 18 countries - from Mexico, across North Africa, the Middle East, Asia, and finally Hawaii. And his adventures have been turned into a six part ´óÏó´«Ã½ television series.
Simon joined Matthew in the Outlook studio to describe his experiences and the people and places he visited, including the female wrestlers of Mexico City.
Tropic of Cancer is on ´óÏó´«Ã½2 at 8pm for six weeks from Sunday 14 March 2010
