Many of my engineers are addicted to the hydrogen I put into the balloon.
Whenever I put hydrogen on, they crowd over to the balloon. If I leave it on too long, they start screaming incoherent babble. (I think they are saying "More balloon, destroy our lungs please!")
And the balloon frequently catches fire or gets destroyed. I think my engineers are either smoking hydrogen, or ripping through the balloon to get at the hydrogen.
So, yea, I'm looking for an engineer who can show restraint when I pop a bottle of hydrogen in the balloon.
