Most people grieve in their own ways, but this is totally extreme. Sword-swallowing therapy is not only dangerous, it can also kill you in the process.
A believer in this sort of therapy is Natasha Veruschka, who holds Guinness World Records for swallowing a 29.5-inch sword while simultaneously swallowing 14 22-inch swords and swallowing a 24-inch sword filled with poisonous neon. Natasha Veruschka's husband passed away last fall, and she has since been using sword-swallowing therapy to help her grieve.
Nicholas Penney is another sword-swallower who states that "to swallow a sword, you have to clear your mind. It's like a form of meditation." I don't know about you, but I prefer some nice and safe yoga for my meditation.
