Summer in London ? Let's try this new startup idea
Aaaah, the summer in London. Pints and Pimms after work, and a 99% chance of waking up the next morning with something like "I should have left before this last drink…” On this project, you have invented a skin patch that detects your alcoholic level, which triggers an alert when it forecasts it's time for you to stop so you can wake up hangover-free the next morning. Think google diabetes lens, re-targeted to the pub culture, and with an easier task of measuring alcohol level from skin sweating than glucose level from eyes (which eventually turn out to be a weak proxy for blood levels).
