When Sister Laura says
You commute to work by bike? How can you do that without getting hit by a car or showing up all sweaty? And what if it rains?

You can say
It's actually pretty easy -- and it's a great workout, which is a bonus if you're looking to stay in shape.

I read a really great "How to Be a Bike Commuter" guide and now I feel like a pro!
