Every good alpha male and female has lots of keys on their keyring. This is a sign you have access to lots of places and are thus more important than people with smaller keyrings. The largest key on my keyring is a Radar scheme key which gets me into disabled loos and other facilities only important people can use. Anyone can buy one with just a confirmation tick box that you're disabled (nothing complex like blue badges here), and those of us with head injuries deserve any help we can get to make life a little easier. If you live near a canal is might also be useful to get a BW key from Scottish Canals or CART to use the various facilities along the canals.
