What is the longest you have laughed?

I can be hurt when I laugh long. My cheekbone to be specific. lol. The last time I laugh so loud and so long was when I was with my office mates. We had a videoke in one of my office mate's house and it was so fun because none of us are not really that good to sing. We know how to sing but we cannot reach those so high tones. We are laughing also because some of our songs came mostly on the 70's and 80's. lol.

I don't know... I mean, I haven't been paying attention to exactly how long I laugh for. But I know I have these hysterical laughing sessions, when I start laughing at a little joke, and it generates itself, and I can't stop laughing, even though my face is read and my face hurts :P. And it's not even that rare. I think they even last for minutes...

I don't know. But I know I have laughed until it hurts. I didn't suffer any real damage, though. It was actually a great feeling.

Well it depends upon the situation, the reason that made me or excited me to laugh, if i laugh long it hurts.. Thanks for this nice discussion.

I wish I'd know the answer to this question too. I have laughed to the point where my abs, jaws, and head hurts from the muscles I used for smiling. Gasping for breathe and holding onto my friends for dear life. Sorry I don't know the answer, but reading this question reminds me of a happier time :). Thanks haha

What a great question:-) I think that if I laugh more than 10-15 min, it will start to hurt. I have tried laughing so hard, that my stomach was still hurting two days later
