Just re-read the last post. Wow – I am a cranky old man.
Things all kids should be taught:
Esperanto (or some one language) – and should be exposed to kids from other cultures on a regulare basis to take advantage of the language so that the study is not academic.
Human body – should be given a user manual. We don’t know the answers to the most rudimentary questions, even though they are out there.
Another interesting web-application: automatic monitoring of sleeping patterns. Can sleep be identified via, for instance, temperature readings? Then a person could wear a thermometer that would continuously record the demperature, upload it to the internet, so that the person could then find the optimal sleeping patterns.
