because when you laugh your brain releases endorphins (a chemical in your brain) that make you feel good. same thing if you run alot, also called runners high. it just makes you feel happy, or better. which is also good if your depressed or something. just run and laugh alot. lol. :)

I'll snort if I laugh really hard unexpectedly. For example if someone tripped infront of me. I love when I snort, it embarasses me so I laugh even harder and all my friends laugh at me so it just goes on and on.

Believe it or not, girls who make us laugh is one of the most attractive traits sometimes. Just be yourself, and whatever comes out comes out. Don't try to impress us, we already notice you for who you are. And honestly, we don't remember half the stuff we hear 5 seconds after we hear it - so its like a fresh start for you every time!

It isn't necessarily the joke that is told but the presentation. Try to relax and tell her an incident that happened to you that you ended up looking or feeling silly, where you can laugh at yourself. Actual events or familiar happenings are far more funnier then a rehearsed joke. Just watch comedians.

lemme know if you find the answer....what's weird is that i don't get embarrassed but seem to turn red whenever i make people laugh....i don't get that....or if i ask a question in front of people...i love the attention but my face just turns red....i've never understood that...i could never be a standup comedian..i'd tell a great joke and just turn into a tomato...but i'm never embarrassed....\nwhat a dumb face..\n-nny

I won't pretend to know the biological and/or psychological mechanisms taking place that is conducive to this. It's just a spontaneous (laugh) reaction that most humans have in response to the stimulus of hearing something funny. We have just marvelously been created and "wired" up that way.\nA word of caution --- what you may interpret as "hearing something funny" is purely subjective. What you may hear and interpret as being funny may not always be perceived the same way to other individuals --- hence, beware that hearing a "funny" joke/experience could potentially become an embarassing situation ... 'nough said.

Can't really explain it. Well the reason for it other than we see something funny and we laugh. I can't explain a laugh but I know laughter is a wonderful form of stress relief. It's very important to have a sense of humor and to be able to laugh and live happy. If you want a scientific background, research etc I have enclosed a few sites. Maybe this will help clear somethings up for you. I also know laughter is very contagious. I was laughing so hard earlier at my husband on the phone I had other people around me laughing just because I was laughing. I was eventually laughing so hard I forgot why I was laughing in the first place! One of the sites listed I think it's the 3rd actually says laughter is good for you and helps your blood vessels function better! Also listed is a book that might catch your interest.

You look in the mirror and have a good laugh at what you see there.\nThat is how you do it.  I have my own humor meter.
