My running joke for the past couple years has been "there's nothing a software developer hates more than computer science". But I guess there was one too many words in that sentence!

As someone fiddling with computers trying to solve "every problem," the only actual solution for me is making tools to assist with being aware of the state of your body. Overly simple example, but give someone a heartrate monitor for the first time and they won't be able to guess their current bpm all that accurately. If they pay a little attention to it for a month, you'll get much more closer guesses for instantaneous rate. If it becomes easier to be aware of your current state, you get a more accurate model, and can start to predict basic cycles etc. Eventually, without the tools.
