interesting..

i was reading readers digest whihcmum always gets,and you can call me said all u like i love the capter called laughs or soemthing its really quite gigly stuff.and there was a bit of weird questions answered.and one was why do we got dry throats when we are nervous,and it explained that its our bodies going into fight or flght moad when our body is in need,so when were nrvous we are obviously scared or in danger of soething,so our bodys go to using all its resources for the important stuff,like blood vessels expand to get blod to our organs to breath or get away and our eyes dilate and our throat is one coz it dries as we dnt need to digest anything at that mment,and our digestive systme isnt needed to get away or preserve ourself so it shuts down like many other things this is also why(this bit is the really cool part i though)we get butterflies in our stomach,it is the feeling of it shutting down and nt working cz we dnt need it for durvival at that point of escape or occurant danger we get when were nervous say of going on stage or bigger things you no maybe escaping from a beast or soemthing!!
