Left-handed women’s quirk over sense of smell

Scientists say they have discovered a biological anomaly that could change how we understand our sense of smell.
The study in the journal Neuron shows some people can smell normally, despite missing the part of the brain that is considered to be crucial for smell – the olfactory bulbs.
Lacking bulbs should cause anosmia (being unable to smell).
Curiously, the phenomenon mostly affects left-handed women, and has never been detected in men.
Senator Elizabeth Warren tweeted:
Left-handed women who lack olfactory bulbs but who can still smell anyway are the #BackboneOfOurDemocracy
