Ah! That moment comes when you feel something so intense that something goes off inside your head. Click! And then your mouth opens in amazement. Or no sound escapes, but the thing is building more and more in there into something bigger, a bigger bubble waiting to pop or explode.
AAAAAAH! means the same as "ah!", but when the sound leaves your opening mouth, it's either in rage or frustration or fear. It's doesn't carry the same feel of euphoria that comes with the ah!
Aha! Sometime were are so amazed we start to laugh and then stop before it turns into laughter, kind of a half-assed laugh, cutting off a laugh like it's something big but not funny.
Ah.......... hahahahah! My personal favorite! You had to think to laugh, you had to look for the hidden joke within. And then that bubble pops and then you realize not only did you make a discovery, but that it's also hilarious.
The thing is, life is a funny thing. Life has a sense of humor, so its so important that you never lose yours or you will forget how to live, you will forget that it's all so silly, just being here and witnessing all the games people play, you will forget to love the time you have and forget to look for humor. When I can no longer laugh at things I have done that used to seem so huge and horrible, when I can no longer laugh at things like sex and death, when I can no longer laugh at all, I am dead.
It doesn't matter that I have a brain or that I can breathe or that I can go through my life and live like I always have. Change, movement, progress, watching, thinking, loving...that's life, but it becomes blocked and life stops when you can't laugh. To me, laughing is like breathing.
