When I worked as an undergrad in the Micro Dept, the grad student I worked
for was a Med Tech by trade and he sniffed everything! We worked together
for 2 years and TA'd together and he was constantly telling me "see, this
smells like burnt chocolate" or "this is fruity smelling". Everyone looked
at him like he'd flipped when he started sniffing cultures but he was
never wrong in his ID!
