Hello Rob.
We're renaissance people.
We have to be good at being, in no particular order, geologist, historian, electrician, software expert, metallurgist, materials scientist, artist, woodworker, architect, jeweller, geographer, photographer, bargain-sniffer, engineer, curator, technologist, mathematician, illusionist, designer. (Feel free to add other disciplines from the arts and sciences and we will tick the yes box.)
