I think I'm one of those people, I hoard running data - all exercise data actually, even swim metrics, the more detailed the better so with running I know my stride length, cadence as well as pace and distance and elevation gain (or loss)
and today I was very excited to finally receive my registration pack after about 9 months for the TDM thing so could log on and admire my lithium levels and renal function and all those things but the fuckers missed off my registration ID so I have to wait a few more days
