Smelling my armpits for no reasons at all.

It has been 7 months since I've been started
working at this place. And for 7 months I
haven't done anything that a sane person
wouldn't do in a very cold enviroment like this.
The temperature here is approximately 16 degrees.
And while I was working, there is a sudden urge
for me to smell my armpits for no reasons at all.
Yes. I've for no reasons at all stuck my
right index finger directly under my right armpit.
Next smell it. And wince. And also the same index finger
under my left armpit which smell worse.
During this 04:53AM, I have no ideas why I did that.

Before that I was talking gibberish to my old friend.
I was talking like I was 5 years ago.
Pure nonsense but it was very funny. To me it sounds funny.
Bloodyhell now I can imagine that flying cat again.
I thought the cat is dead?

Now I'm thinking of what to do next.
