If I do that I'll have a really bad asthma attack." "Okay, fine.

I am a hemophiliac.
If I do that, I'll bleed to death." "Well, then we need a urine sample." "I'm sorry officer I can't do that either.
I am also a diabetic.
If I do that I'll get really low blood sugar." "Alright then I need you to come out here and walk this white line." "I can't do that, officer." "Why not?
