    1. How many beans does a 415g can of Heinz Baked Beans contain, on average?

    2. The World Health Organisation recommends that you can safely listen to headphones (slang: "cans" - geddit?) at a sound level of 80dB for up to 40 hours a week. If the sound level is 90dB, the safe listening time reduces to ... what?
