Back in the day..
before all this automation and on-board processing malarkey, mine surveying used to involve a person at a fixed point throwing a laser beam at a person at the work location - who would bounce it back, and by various arcane mathematic and mechanical rituals, useful information would be derived. As the fixed point and work location could be up to a kilometer or even more apart, a 2-way radio ("walky-talky" for people who like to talk like children) was an essential part of the kit.
All the 'laser' controls were set up for right handed control, on the other end the laser-bouncy stuff pretty much required being managed by your dominant hand - so the 2-way was held in the left.
Which is why I talk left-handed.
....I want a derail/off-topic icon...
......is it even possible to go off-topic from Dabbsy comments ?
