1020: Mucosa Sep 24, 2017

-
There is somewhat of a stereotype that opera singers are larger than average. Though generalizations like these are often unfounded, David Drexler et al. from the University of Iowa found that a certain amount of fat on the vocal cords can help a singer sound better. A mucosa on the vocal chords softens the impact when they come together, but extra amounts can improve the quality of sound. It was also found that the mucosa can add more vibrational energy to air as it is exhaled, which also allows opera singers to perform better. There are many other factors that come into this as well, and it is not at all the case that all opera singers are overweight at all, but having extra fat in general could mean there is some extra fat on the mucosa. Also, sometimes when one has scarring on the throat, surgeons can inject more fat onto the larynx for this same reason.

Check out the latest podcast on the Patreon for as little as $1: • It is very easy for misinformation to spread so long as there is a grain of truth to it, such as the line of ' let them eat cake ', which was probably never said by Marie Antoinette. Another such disputed quote is "I return in 3 (or 5 or 8) days; don't wash" said by Napoleon to his wife Josephine. This quote is more likely to have been written than that attributed to Antoinette as he did often write her love letters, but many of the original lines from which the now-famous quote could have been drawn are often contradictory or not so reliable.

852: delilah Apr 8, 2017

Plenty of common Western names have some biblical relevance. It is usually from the frequency of these names that terms like 'john' referring to a man who hires prostitute, or foundation the baseball team, Yankees , come about. Some names, such as 'Delilah', are also used as nouns separate from the name, but with connotations stemming from Scripture, and not contemporary connotations. It is from the story of Samson and Delilah where the sense of the word as 'seductress' began, but the name was around for much longer than this. There is disagreement concerning the true etymology of this word, but it either comes from the Hebrew element 'dal' meaning 'weak' or the Hebrew for 'delight'. Unlike other much older names like 'Matthew' or 'John', 'Delilah' only started to be used as a name in the 17th century with the Puritans, though it gained more popularity following Saint-Saens' opera, Samson and Delilah (1877).
