The data will hopefully make sorting out environmental triggers of the disease much easier -- it took scientists eight years to prove that soybean dust near the Barcelona harbor caused a massive asthma outbreak in the 80s, a timeline that might have been dramatically shorter if location information had been available from the start. The plan's still in the early stages, but would-be participants can sign up already -- let's just hope the tracker is slightly more attractive than Kogan's enormo
