How do you work out gear ratios

enjoy your drugs-reefers, but I hope you don't do it too long and end up like those twitchy, bedraggled weirdy-beardy old stoners (who carried on smoking after all their friends gave up and started playing golf and cleaning their cars) who constantly mutter, bitterly, about conspiracy theories and "them" then stick silver foil over the electrical sockets in case "they" get "in"

When did we meet and do you want to buy an anodised tin foil hat to shield you from the voices?

Although I think I would rather be mad and paranoid than play golf or clean my non existent car.

I had friends like that once, their wives won't let them speak to me anymore.
