You've got two nostrils, so sniff them two at time and take half as long.

That got me laughing but being the serious kind I am now wondering if we're wired up in such a way that if one tomato is bland and the other is rich in smell that we can tell the two apart reliably enough to know which is which?

I always think of us as having two eyes, two ears for stereo vision and sound but never think of us as having 'two noses' to determine the direction of a small or two different smells at the same time.

I live in Amsterdam but I always try how strawberries smell before buying. And in my experience they smell the same if they come from true same batch so I only need to try once.
