IN: Terence Kemp McKenna (November 16, 1946 - April 3, 2000) was an American ethnobotanist, mystic, psychonaut, lecturer, author, and an advocate for the responsible use of naturally occurring psychedelic plants. He spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, environmentalism, and the theoretical origins of human consciousness. He was called the "Timothy Leary of the '90s", "one of the leading authorities on the ontological foundations of shamanism", and the "intellectual voice of rave culture". McKenna formulated a concept about the nature of time based on fractal patterns he claimed to have discovered in the I Ching, which he called novelty theory, proposing this predicted the end of time in the year 2012.

In 1965, McKenna enrolled in the University of California, Berkeley and was accepted into the Tussman Experimental College. In 1967, while in college, he discovered and began studying shamanism through the study of Tibetan folk religion. That same year, which he called his "opium and kabbala phase" he traveled to Jerusalem, where he met Kathleen Harrison, who would later become his wife.  In 1969, McKenna traveled to Nepal led by his interest in Tibetan painting and hallucinogenic shamanism. He sought out shaman of the Bon tradition, which predated Tibetan Buddhism, trying to learn more about the shamanic use of visionary plants. During his time there, he also studied the Tibetan language and worked as a hashish smuggler, until "one of his Bombay-to-Aspen shipments fell into the hands of U. S. Customs." He then wandered through southeast Asia viewing ruins, and spent time as a professional butterfly collector in Indonesia.  After the partial completion of his studies, and his mother's death from cancer in 1971, McKenna, his brother Dennis, and three friends traveled to the Colombian Amazon in search of oo-koo-he, a plant preparation containing dimethyltryptamine (DMT).  Instead of oo-koo-he they found fields full of gigantic Psilocybe cubensis mushrooms, which became the new focus of the expedition. In La Chorrera, at the urging of his brother, McKenna was the subject of a psychedelic experiment in which the brothers attempted to bond harmine (harmine is another psychedelic compound they used synergistically with the mushrooms) with their own neural DNA, through the use of a set specific vocal techniques. They hypothesised this would give them access to the collective memory of the human species, and would manifest the alchemists' Philosopher's Stone which they viewed as a "hyperdimensional union of spirit and matter". McKenna claimed the experiment put him in contact with "Logos": an informative, divine voice he believed was universal to visionary religious experience. The voice's reputed revelations and his brother's simultaneous peculiar psychedelic experience prompted him to explore the structure of an early form of the I Ching, which led to his "Novelty Theory". During their stay in the Amazon, McKenna also became romantically involved with his interpreter, Ev.  In 1972, McKenna returned to U.C. Berkeley to finish his studies and in 1975, he graduated with a degree in ecology, shamanism, and conservation of natural resources. In the autumn of 1975, after parting with his girlfriend Ev earlier in the year, McKenna began a relationship with his future wife and the mother of his two children, Kathleen Harrison.  Soon after graduating, McKenna and Dennis published a book inspired by their Amazon experiences, The Invisible Landscape: Mind, Hallucinogens and the I Ching. The brothers' experiences in the Amazon would later be the main focus of McKenna's book True Hallucinations, published in 1993. McKenna also began lecturing locally around Berkeley and started appearing on some underground radio stations.

input: On March 13, Roethlisberger signed a five-year contract extension with the Steelers. Roethlisberger went 26 for 38 for 351 yards, one touchdown pass and one interception during a 28-21 loss against the Patriots to kick off the 2015 NFL season. However, Roethlisberger and the Steelers would bounce back to win their next two games against the San Francisco 49ers and the St. Louis Rams. In the 43-18 victory over the 49ers, he had 369 passing yards and three touchdowns to earn AFC Offensive Player of the Week.  During the September 27 game against the St. Louis Rams, Roethlisberger suffered a sprained MCL and a bone bruise. Roethlisberger missed the Steelers' next four games, during which Michael Vick and Landry Jones combined to go 2-2.  Roethlisberger sustained another injury against the Oakland Raiders on November 8, 2015, suffering a left mid-foot sprain. Due to this injury, he did not start the following week against the Cleveland Browns, although he was listed as active for the game. However, early in the first quarter, Landry Jones sprained his left ankle, resulting in Roethlisberger entering the game in relief for only the second time in his career. Roethlisberger threw for 379 yards and 3 touchdowns on the way to a Steelers win and an AFC Offensive Player of the Week award; his 379 passing yards were the most by a quarterback in relief since Don Strock threw for 403 yards in the Epic in Miami. On November 29, Roethlisberger threw for 456 yards against the Seattle Seahawks, but he also threw 2 interceptions, and the Seahawks took a 39-30 win.  The Steelers clinched a playoff spot with a 10-6 record, finishing second in the AFC North behind the Cincinnati Bengals. They then defeated the Bengals by a score of 18-16 in the Wild Card round, but lost to the eventual Super Bowl champion Denver Broncos in the Divisional round by a score of 23-16. Roethlisberger was named to his fourth career Pro Bowl and was ranked 21st by his fellow players on the NFL Top 100 Players of 2016.
