As my e-mail address indicates, I am a biologist. People sometimes ask me why. After much serious thought, I came up with this explanation: (Yes, it is original -- mine, completely mine.)

When I first started out, I was going to be a mathematician. So I took algebra, but I found that was highly variable.

So, I tried geometry. And that's where I learned all the angles.

Then I took calculus. That was truly an integrating experience, but it definitely had its limits.

After a great deal of consideration, I decided to turn away from math and give some serious thought to science.

I tried geology, but found that was kind of hard.

Next I tried physics but I knew that would never work.

And even though I'd heard chemists had all the solutions, I finally opted for biology because, after all, it's a living.
