I guess every religion old enough has such kind of loopholes. I know from Roman Catholic that there can be made up so many exceptions that the 40 days of lent before Easter books down to a few days of actually fasting. No lent if you’re travelling (commute to work counts), no lent if you have guests, and of course no lent if you are a guest somewhere else. And Sunday is exempt from lent anyways.

The permit requirement does not apply to kitchen knives, does it? Been some time, but I travelled to Tokio quite frequently for work, and always made it a point to go to kappabashi and get a nice cooking knife, some of the longer than 20 cm.

Theranos sounded like a superhero villain. I guess it kind of was?
