I've been to Mammoth Cave a few times. I have a great fear of caves and tunnels but I went anyway. It's amazing and so worth a trip to view it.

18 motors? The more parts the greater the chance of breaking down. I would think less parts would be better and easier to fix.

Tooth worms? Well, that explains a lot. And after all this time I find my dentist disagrees with that bit of info. Like he's an expert or something...

Those shoes . . . To quote an amended Santa's comment: "You'll shoot (poke) your eye out, kid."

I wonder what kind of kidney stone it was. Some are calcium based while others are formed from other minerals. I had hoped the article would have said what the composition of the stone was made of.

That picture looks like a ball of rotten cheese.

Back in the 90's it occurred to me that I really missed playing on a playground when I was a kid and that if I were very wealthy I would open a chain of playgrounds for adults. Who doesn't miss using a swing set or a jungle gym? How about climbing up a rope ladder? No barbells and weight lifting items, no stationary bikes. Just a big old playground with a pool, too. I really think they would have been immensely popular.

"Great Tits". I can't tell you how many times I've heard that in my life.

I always travel with a gun and a door wedge. The gun is because of my business selling fine jewelry and the door wedge prevents anyone entering your hotel room uninvited. I encourage children to keep a door wedge in their backpacks because of the school shootings so prevalent today.

Having spent a good portion of January and February of this year in 2 hospitals for kidney stones my heart goes out to this poor guy. I feel your pain, sir! Get well soon.

It looks like it's alive and in anguish when stimulated.

I used to teach at real estate school so students could pass their state and national exams. I taught them how to use a legal cheat sheet which involved lots of memorization. You made a long list of information you needed to learn, numbered the items and then proceeded to shorten the info per line over and over until you could look at a listed number and know what each numbered line stood for. When you went to take your tests you were allowed blank paper to use. As soon as the tests started you would take a blank sheet, number your list and write out the info. It was imperative you did this before opening your test booklet because the exams were written in a way that the first 5-10 questions could blow you out of the water and mess with your mind. Having your 'legal' cheat sheet let you have the perfect info for your qustions. A lot of work you say? Yep, but the standard passage rates for first time testers was 55%. ALL of my classes had an 85% passage rate. It worked but you had to really apply yourself to pass.

I tried to find the full list to no avail. Be that as it may, I believe my home state of Massachusetts would be impossible to nimble from a graham cracker.

Never get in a fight with a chimp holding an ax. A lesson well learned from my time spent harassing chimps at the local zoo. They can get so touchy.
