My 91 year-old MIL is quite computer savvy, and I think it helps to keep her mentally sharp and engaged. Or maybe she’s just mentally sharp and engaged, which is why she’s computer savvy. Chicken and egg. Every few days she sends me an internet joke. This one had me laugh out loud:

First-year students at the Purdue Vet School were attending their first anatomy class with a real dead cow.  They all gathered around the surgery table with the body covered with a white sheet.

The professor started the class by telling them, “In Veterinary medicine it is necessary to have two important qualities as a doctor.  The first is that you not be disgusted by anything involving the animal’s body.  For an example,” the professor pulled back the sheet, stuck his finger in the butt of the cow, withdrew it, and stuck his finger in his mouth.

“Go ahead and do the same thing,” he told his students.  The students freaked out, hesitated for several minutes, but eventually took turns sticking a finger in the butt of the dead cow and sucking on it.

When everyone finished, the Professor looked at them and said, “The second most important quality is observation.  I stuck my middle finger in the cow and sucked on my index finger.  Now learn to pay attention.  Life’s tough, but it’s even tougher if you’re stupid.”
