Answer the question at the end by quoting:

Sergio Santos Mendes (Portuguese pronunciation: ['seRZju 'satuZ 'medZiS]; born February 11, 1941) is a Brazilian musician. He has over 55 releases, and plays bossa nova heavily crossed with jazz and funk. He was nominated for an Academy Award for Best Original Song in 2012 as co-writer of the song "Real in Rio" from the animated film Rio. Mendes is married to Gracinha Leporace, who has performed with him since the early 1970s.
Mendes was born in Niteroi, Brazil, the son of a physician. He attended the local conservatory with hopes of becoming a classical pianist. As his interest in jazz grew, he started playing in nightclubs in the late 1950s just as bossa nova, a jazz-inflected derivative of samba, was emerging. Mendes played with Antonio Carlos Jobim (regarded as a mentor) and many U.S. jazz musicians who toured Brazil.  Mendes formed the Sexteto Bossa Rio and recorded Dance Moderno in 1961. Touring Europe and the United States, Mendes recorded albums with Cannonball Adderley and Herbie Mann and played Carnegie Hall. Mendes moved to the U.S. in 1964 and cut two albums under the Sergio Mendes & Brasil '65 group name with Capitol Records and Atlantic Records.  Sergio became full partners with Richard Adler, a Brooklyn-born American who had previously brought Bossa Tres plus two dancers, Joe Bennett and a Brazilian partner, to appear on The Ed Sullivan Show, in 1963. He was also accompanied by Jobim; Flavio Ramos, and Aloisio Olivera, a record and TV producer from Rio. The Musicians Union only allowed this group to appear on one TV show and one club appearance (Basin Street East) before ordering them to leave the U.S. When the new group, Brasil '65 was formed, Shelly Manne, Bud Shank and other West Coast musicians got Sergio and the others into the local musicians union. Adler and Mendes formed Brasil '65, which consisted of Wanda Sa and Rosinha de Valenca, as well as the Sergio Mendes Trio. The group recorded albums for Atlantic and Capitol.

What did he do next?

Mendes formed the Sexteto Bossa Rio and recorded Dance Moderno in 1961.

IN: Nicholas Culpeper (probably born at Ockley, Surrey, 18 October 1616 - died at Spitalfields, London, 10 January 1654) was an English botanist, herbalist, physician, and astrologer. His published books includes The English Physitian (1652), i. e. the Complete Herbal (1653 ff), which contains a rich store of pharmaceutical and herbal knowledge, and Astrological Judgement of Diseases from the Decumbiture of the Sick (1655), which is one of the most detailed documents known on the practice of medical astrology in Early Modern Europe. Culpeper spent the greater part of his life in the English outdoors cataloguing hundreds of medicinal herbs. He criticized what he considered the unnatural methods of his contemporaries, writing: "This not being pleasing, and less profitable to me, I consulted with my two brothers, Dr. Reason and Dr. Experience, and took a voyage to visit my mother Nature, by whose advice, together with the help of Dr. Diligence, I at last obtained my desire; and, being warned by Mr. Honesty, a stranger in our days, to publish it to the world, I have done it."

Influenced during his apprenticeship by the radical preacher John Goodwin, who said no authority was above question, Culpeper became a radical republican and opposed the "closed shop" of medicine enforced by the censors of the College of Physicians. In his youth, Culpeper translated medical and herbal texts such as the 'London Pharmacopaeia' from the Latin for his master. It was during the political turmoil of the English civil war, when the College of Physicians was unable to enforce their ban on the publication of medical texts, that Culpeper deliberately chose to publish his translations in vernacular English as self-help medical guides for use by the poor who could not afford the medical help of expensive physicians. Follow-up publications included a manual on childbirth and his main work, 'The English Physician', which was deliberately sold very cheaply, eventually becoming available as far afield as colonial America. It has been in print continuously since the 17th century.  Culpeper believed medicine was a public asset rather than a commercial secret, and the prices physicians charged were far too expensive compared to the cheap and universal availability of nature's medicine. He felt the use of Latin and expensive fees charged by doctors, lawyers and priests worked to keep power and freedom from the general public.  Three kinds of people mainly disease the people - priests, physicians and lawyers - priests disease matters belonging to their souls, physicians disease matters belonging to their bodies, and lawyers disease matters belonging to their estate.  Culpeper was a radical in his time, angering his fellow physicians by condemning their greed, unwillingness to stray from Galen and their use of harmful practices such as toxic remedies and bloodletting. The Society of Apothecaries were similarly incensed by the fact that he suggested cheap herbal remedies as opposed to their expensive concoctions.

why did he oppose them?
