lol

KCee J says:

Although this may sound like a stupid question, I am curious. With what was said about the kangaroo rat and the beaver, does this mean that a beaver would die almost instantly of dehydration if displaced from his natural habitat to a very dry land and a kangaroo rat suffer from water retention if moved to a place abundant with water? I must know!

Your videos are awesome, love the humor, love the colorful graphics and the information is concise but covers the important points.  I used your videos to study for my massage therapy exam instead of reading the books….Keep doing what you do!!!!!
