One of my friends is studying medicine and I asked why did she decide to study in that field.

her: well, I have a theory. I think it’s because I have a short attention span. I tend to change subjects every two years as I get bored of them easily. Medicine is one subject I think I wouldn’t get bored too easily and it should have enough things to keep myself and my so-called attention span busy. And I like to prescribe medicine for people. What about you? why computer science?

me: because it talks back to me.

her: Oh! you are weird! I just know a medicine I ought prescribe for you!
