But it might lower the cost of travel to and from Kenya, which would enable more people to travel, in turn increasing all the benefits that travel can bring—tourism dollars, trade, and investment."

Top Ten Ways Churches Drive Away First-time Guests

The most frequent response: "Having a stand up and greet one another time in the worship service. This response was my greatest surprise for two reasons. First, I was surprised how much guests are really uncomfortable during this time. Second, I was really surprised that it was the most frequent response."

Most Planets in the Universe are Homeless

"We normally think of planets as being synonymous with gas giant or rocky worlds orbiting a parent star. They should all be so lucky."

What's the best way to brush teeth? Even dentists and dental associations don't agree
