Exist
Micro-analysing ones life in this manner is wrong and counter productive on so many levels.<p>Knowing how many tracks you listen to a day is interesting trivia only.<p>Knowing how long you sleep for each night could be useful, but only if you have a problem with sleep and know, scientifically, what you're looking for. If you're consistently missing out on sleep and feeling ill as a result, you shouldn't need exist.io to tell you this. And if you're not feeling unwell or having sleep problems, then you shouldn't need exist.io to tell you this either.<p>Knowing the number of steps you take is also irrelevant unless it's part of some very slow burn exercise regime you're on, in which case you'd presumably count them anyway. If you're doing normal exercise, steps and heart-rate may be of interest, but only during the exercise period.<p>In short, knowing all of this info about yourself is not helpful. When it lacks greater context and, unless you know how to interpret it, is just a source of confusion and anxiety. At best, it's novel trivia.
