You know you're getting older when...

... something on your desk that you've been frantically searching for in the last few days stares you in the face after you've given up looking.

... you start thinking about your bank account in terms of how long it will last if you lose your job, instead of how many new gadgets to get.

... ride comfort is as important as torque.

... hobby equipment is justified as "investments" instead of "cool stuff", and costs a whole ton more than it used to.

... your colleagues start talking about "biological clocks".
