I'm no spring chicken

On Monday nights I have a Biology lab class. I really enjoy this class which is surprising because I typically don't do well in Math or Science classes and therefore do not enjoy them. But this class is actually interesting. I do notice that everyone in my class seems to be about 12. No seriously they are probably 18, but good grief that makes them TEN years younger than I am. Tonight my teacher (who is also probably 18) asks if we have ever used a microscope before. I paused to try to remember...where there even such things as microscopes back in the dark ages of 1990? That is after all when I took Biology in high school. I am sorry to say that I couldn't remember either way. This lack of memory naturally just proves that I'm getting old....
