IIRC my beard and hair started greying simultaneously (fairly early on too), but don't really remember....but both turned white not that many years later (in my 30s).
I started that video, being a cyclist and mechanic, but that voice was pretty annoying, couldn't handle beyond that first bit

Sometimes you use lube, sometimes loctite on threaded items....but hopefully Dan can keep the loctite out of the equation
