Something really fascinates me about medicine... it's so incredibly difficult to actually tell if anything works!

I mean look at the debates over antidepressant drugs. There are some large studies that claim most are no better than placebo, and others that claim otherwise.

I feel like there has to be room for improvement here. Maybe we need to start learning to go beyond large studies at a distance and start really measuring things in real time, e.g. with something like an evolved connected descendant of the FitBit.
