The science of laughter | Sasha Winkler
b'
Isn\\u2019t it odd that, when something\\u2019s funny, you might show your teeth, change your breathing, become weak and achy in some places, and maybe even cry? In other words, why do we do this bizarre thing that is laughter? Since there\\u2019s no archaeological record of laughter, it\\u2019s impossible to say exactly how and why it evolved, but scientists have some theories. Sasha Winkler digs into the reflex. This TED-Ed lesson was directed by Hanna Rybak, narrated by Susan Zimmerman and the music is by Jarrett Farkas.
