Look It Up

Look It Up is a podcast for the indiscriminately curious. On this week's episode: why do I get so cold in a hammock? Which type of transport is safest per mile traveled? Where did the names for the days of the week come from?   Sources: transportation statistics from the NTSB and IIHS, bit.ly/liutransport1, bit.ly/liutransport2, and bit.ly/liutransport3. Weekday etymologies on Wikipedia, bit.ly/liuweekdays.
