Yeah, monitoring your heart rate and breathing is a short step away from cataloging your sex life, or at least the part of it that takes place in bed, which is where most people like to get it on.

I am not that enthused about this whole 'quantified self' movement; it strikes me as Taylorism applied to leisure activities and now sleep. I have no confidence that the data will remain fully under user control; rather, incentives will appear that encourage people to grant non-revocable access for consumerist 'rewards,' which in turn will be employed to create consumer anxiety about suboptimal life patterns, which can be assuaged for the low, low cost of only $x/month.

I like technology a lot, but I don't care for the idea of being cocooned by it 24/7.
