I used to laugh heartily, you know, laugh hard, sometimes at length, and your stomach muscle hurts, etc, like everyone I know. In the recent years, every now and then, something would really *strike* me funny, and I'd laugh hard... but then while laughing really hard, I lose all my strength, and I practically collapse! Sounds funny and typical, bu no! I can't for the life of me stand on my own two feet. When I'm laughing and it really gets going, I almost seem to convulse a bit, because I'm losing control, and I need to hold onto something before I fall! I mean, I'm not concerned that it's a disease or anything, but I'm just curious as to why this happens... am I the only one? I was thinking because I'm laughing so hard, my diaphragm is getting a good sudden workout, and the wind is being knocked out of me??
