Extracting a porcupine quill is painful and sluggish, as many a pet uncovers to its discouragement after tangling with the huge rat. But those tenacious quills are impressive efforts to establish better medical devices, including less painful needles. It turns out that nobody had actually truly selected apart why it's so difficult to remove a porcupine quill. Barbs, sure. But the barbs not just stick like mad. They likewise make it much easier for the quill to pierce skin and flesh. "We found the barbs have this dual functionality," states Jeffrey Karp, a bioengineer and a chairman of the Center for Regenerative Therapeutics at Brigham and Women's Hospital in Boston. "That was a surprise.". It doesn't seem to make good sense that a barbed quill would go in even more easily than a hassle-free one.

- Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
- The Mean is meant to be an indicator of an individual's average comment sentiment.
- The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).
Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.

The barbs on porcupine quills help them pierce the skin. If the bumpy needles work so well for the big rodents, couldn't they they also help doctors and nurses giving injections? Designers of medical devices are looking to try the porcupine approach.
