Last July, while wandering about the coastal forests of St. Lucia in eastern South Africa, I happened across an intriguing scene half-way up a spiny Acacia trunk. Some diminutive gray flies were pestering a trail of ants as they walked along the tree.
The flies' exact activities were hard to observe with the naked eye, but it looked like nothing I'd ever seen. They seemed to be grabbing ants, pinning them to the trunk, and after a few seconds letting them go again.
The macro lens on my camera serves as a handy field microscope. Conveniently, the flies were so focused on attacking the ants I could place the lens nearly on top of them and observe the details of their activities without spooking them. On inspection, it turned out that the flies were stealing food.

Of course you can always cheat and stay clean by eating lots of pasta, bread and salty snacks...
The pill was introduced in Europe a long time ago and it's called Xenical.
My brother, who builds fences, almost tried it.

ps- is that a typo--does her brother build fences or feces?
I have been taking it for a month now and have learned that if I consume a high fat meal, I will suffer the consequences. Alli has helped me. 8 pounds in 3 weeks is a major accomplishment. And just the thought of having a horrifying episode like one described in the article has taught me to prepare and enjoy a lower fat diet.
