Newlyweds whose romance started online. Erin: Love is putting the other person first.

Mike and Alanna Clear married at the end of 2008, three years after a blind date. Instead of a wedding list, they asked friends to help send them on an adventure, and gave it a purpose.
In June 2009 they put their new marriage to the test in the lab. Scientists examined their relationship and made a prediction: would they stay together for life? Then they took that prediction in a sealed envelope to Alaska, and rode a motorbike and sidecar 20,000 miles down the Pan-American Highway to the tip of Argentina.
On the way they interviewed more than 120 couples and asked each of them for their advice on going the distance.
Would the newlyweds go the distance themselves?

Every couple got the same five questions: their names, how long they'd been together, how they met, their advice, and what love is.

Tayo: Giving is everything. If she asks you for something, then you give it to her, because she is part of your body.

They met in a choir, and both had to get over their shyness to fall in love.
