Have you ever noticed how much we laugh? We laugh at everything. We laugh at jokes and pratfalls and even other people’s sufferings. We make a remark and then laugh thinking if the other person doesn’t understand they will think it is a joke and laugh back.
We laugh at animals and children just doing whatever they do naturally. We laugh when someone falls not worried about what injury may follow. We laugh at ourselves and at others. Some people make a livelihood off of knowing how to make us laugh.
I guess it beats the alternative.
