It should be done like cs:s and teamkills/hostage kills
Also: I'd like to play
Also also: Dying from not washing yourself or going to the bathroom? Why not replace going to the bathroom with having an injury and needing a medkit and washing yourself with having to take some medication that you need?
And each one should hinder you, but if you complete it fast enough it gives you a slight bonus.
I like lines :D
