yeah im gonna need it. i passed out in bio lab last semester (well fall actually). our teacher (a grad student) pulled out this cow heart that was soaked in formaldehyde. this damn thing was about the size of my freakin head! and it was cut in half so you could see the interior chambers (atria and ventricles). i hadnt had anything to eat that day and add the smell of the formaldehyde which made me woozy, i went out when she opened the thing up. it sucked hard!
