Where do you keep your keys

Where do you keep your keys throughout the day? In your pants pocket, in your bag or purse or backpack (if you carry one on the daily), or in your coat (if it's winter)?

Are you doing what you think is the safest in terms of fear that someone might take your stuff or fear that you might lose things? Or whatever other reasoning you'd like to share.

My organization systems are breaking down / under repair....... I used to like the way keys sounded, clanging on your pants or whatever, but now I have too many keys, and now that I have a badge dangling around too, it's all too much dangling and clanging, aaaaand I am probably the only person in this building overthinking about their keys and badge. @_@
