Daisy is a Diesel

I was curious about my little monster of a cat recently, and I found a wealth of info. on why cats purr. I already knew that it was a voluntary action, and that it could show pleasure or a "please don't hurt me anymore- I'll be a good kitty" kind of response, but I didn't know the following information:

"It seems that the measurable Hertz of a cat's purr lies between 25 and 150. Coincidentally (or not) it has been found that sound frequency in this range can stimilate bone growth and healing."

The article that I read also said that sometimes a cat's purr can be around 26 Hertz, and that this is nearly identical to that of a diesel engine. Does that mean that Long Haul driving could be physical therapy?
