Actress, comedian, and personal hero Amy Poehler was rehearsing for Mad Men star Jon Hamm’s debut on Saturday Night Live when she got the call her OBGYN died just days before she was due to deliver her first son, Archie. Amid her hysterical panic, Hamm grabbed Poehler by the shoulders and jested this was a very important show for him and he was going to need her to get her sh*t together. Poehler, as she described in her new memoir Yes Please, said she laughed so hard she thinks she peed.

“Going from crying to laughing that fast and hard happens maybe five times in your life and that extreme right turn is the reason we are alive, and I believe it extends our life by many years,” she wrote. While the jury is out on longevity, science does find laughter boasts some major health benefits. BuzzFeedBlue — one of several BuzzFeed channels on YouTube — rounded some of them up and put them into a video we inspires laughter in its own right.

Laughing, it turns out, inadvertently improves everything from our love lives to our digestion. A study published in the journal Evolutionary Psychology found women perceive funny men as more intelligent, and ultimately, as better providers. Enter: every dating profile you’ve seen that is seeking a partner with a sense of humor. BuzzFeed also cited research that found laughter balances blood pressure, which leads to better circulation and digestion.
