I've been led by my nose all my life and tried to make perfume by boiling sugar water in jam jars and stuffing them full of gardenia and rose petals when I was growing up in Swaziland.

Smell is the shortest synaptic leap in the brain to our memory, and I'm amazed that people don't sniff everything.

Everything I dared dream of has come to fruition. Which is not to say that I don't grumble with the best of them, but the wobbles have been way outweighed by the wonders.

Proving yourself in a field where the casualty rate is so notoriously high is an ongoing challenge.
