I'm relatively new to QS, but I really enjoy data and the idea of quantifying daily life to look for patterns that may eventually lead to a an improvement in energy, stress, rest, etc. Needless to say, lurking around this forum has been very helpful.
I recently bought a Jawbone UP, and am very interested in the data it makes available in CSV format. I've perused the output, and the column definitions posted (thanks for linking it, Ernesto). I'm curious about what folks are doing with this data for their own projects.
The Jawbone UP is only one source of data, I'm getting becoming familiar with others, including homebrew solutions making use of both manually gathered and automated data, and as I collect, I'd love to hear about what anyone is doing with their UP data exports.
