Another silly poll

A discussion at the pub today resulted in the startling realisation by me and flatmate and a friend that not everyone can smell cucumber. We all agreed that we can smell a freshly-cut cucumber at probably 5 feet away, whilst some of the other people present reckoned they wouldn't be able to smell one if their nose was an inch away.

This led us to wonder where cucumber-smelling is a single-gene ability, like tongue-rolling, freesia-smelling and PTC-paper-tasting.

In preparation for what shall surely be a ground-breaking Nature paper, I wish to conduct a survey...
