A joke

Therapist to new patient: What brings you here?

Patient: It’s my job. I teach schoolkids about evolution. It’s your genes that make you who you are and tell you what to do, I tell them. Evolution happens when new genes enter the gene pool--new genes come from old genes getting damaged then natural selection determines whose genes get passed on.

Therapist: That seems OK to me. So what’s the problem?

Patient: The problem is, it makes my own life seems so meaningless. I’m determined by my genes. All that seems to matter is our own species continuing to evolve. But what can I contribute to that? Getting my genes damaged through radiation, that’s all I can think of. It’s so depressing.

Therapist: Then why not get another job?

Patient: What! And give up science!
