the app asked for my gender and birthday, which I provided because I figured they were probably using it to set up bar graphs etc in addition to selling it to random corporations.
then it asked height, with my current height already set, and then it asked for my weight with nearly my current weight set (off by 3 lbs)
eerie. but I think these were just demographic averages. thus, I conclude this: according to the "Polar Beat" exercise app, I am a perfectly average 36 year old woman 😌
