(b) There is no peer-reviewed medical report on Covii products.

Sales Brochure; The Covii hand. Covii, undated

, whose page 3 states, "COVVI is a portmanteau of the Latin 'Coperor' and 'Vita’ 'translating as 'working together [co-]' and 'life'[, respectively]."  Elsewhere in the website, it states that two v's means plural (in the firm's thinking, definitely NOT Latin grammar --indicating working together to improve MANY lives).

at page 12: "To keep hands up to date with the latest features, we offer quarterly software updates which can be done remotely without the need for the hand to come back to our office."

Note:
(a)
(i) Compare Christine Lagarde
https://en.wikipedia.org/wiki/Christine_Lagarde
(1956- ; President of the European Central Bank 2019- ; Managing Director of IMF 2011-2019; "She graduated from Paris Nanterre University, where she obtained master's degrees in English, labour law, and social law.[20][21] She also holds a master's degree from the Institut d'études politiques in Aix-en-Provence")

These are the highest degrees she obtained (with which she started out as an attorney); she did not get a PhD (or JD).
(ii) The French surname Lagarde (not de Lagarde) is from place "name from Lagarde or La Garde names of several places in various parts of France named in Old French with garde 'watch protection' (see panother French surname] Garde)."
(iii) (Modern) French-English dictionary:
* garde (noun masculine or feminine from context; plural gardes): "watch, guard"
https://en.wiktionary.org/wiki/garde
   ^ The English noun or verb guard came from Middle English garde. (Middle English was what People in England spoke following the 1066 Conquest.

(b) "Sarah was on the tracks for 15 minutes before the alarm was raised." Another report about her said that after fifteen minutes someone finally heard her cries and looked down.
(c) London's Air Ambulance Charity
https://en.wikipedia.org/wiki/London%27s_Air_Ambulance_Charity
("The charity was founded in 1989 by General Surgeon Dr Richard Earlam in response to a report by the Royal College of Surgeons, which documented cases of patients dying unnecessarily because of the delay in receiving prompt and appropriate medical care. The charity was the first in the UK to carry a senior doctor in addition to a paramedic at all times on a helicopter, introducing a system that reduces the death rate in severe trauma by 30–40%")
(i) Richard John Earlam (1934 - 2016) was a consultant general surgeon at the Royal London Hospital. You see, "general surgeon" is not a title (so should not be capitalized as Wiki does), but a surgeon who performs general surgery.
(ii) London's Air Ambulance Charity relies on donation for its annual budget of about 15 million pounds. Its service is free.
