Die... Laughing?

I don't understand why my asthma attack is happening too frequently lately.

It's irritating, disturbing, and worrying.

I even dreamed of having an asthma attack due to excessive laughter and was only able to breathe like 10% of air to my lungs.

And it DID happen to me in reality. My asthma attack comes more frequent when i laughed too much than when i'm cold. It never happened before, my asthma problem RARELY gives problem to me in the past, even when i laughed like hell.

But now it does.

How if my cause of death is.... due to laughter?

OMG~ O.O
