How many shrimp do you have to eat before it makes your skin turn pink?

it is easy for an animal with white coloured meat by design/nature to turn pink quickly, but considering you are human, you have a red coloured meat/flesh, the quantum of Krill or Shrimp shell that you need to eat would basically kill you by the time you actually turn pink.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.

it doesn't. it was imagined up in the middle ages.
