official report stated that he choked on his vomit, but the accounts

reportedly changed the view, but Asphyxia due to aspiration of vomit;
contributed to by barbiturate intoxication is still stated as the cause.

KEEPING TIME
 
       “Time” has been defined as the sequence of existence into a series or
sequence of events that can’t be reversed. With that said, some
scientific theories argue it’s possible to change the sequencing.
 
            Water clocks were the most reliable early clocks. The oldest
examples of water clocks come from 16th century BCE Egypt and
Mesopotamia.
 
            The “grandfather paradox” holds that if a time traveler were able to
go back in time and kill their grandfather then the time traveler
wouldn’t be born. But if the time traveler wasn’t born, then they
couldn’t go back to kill grandpa, right?
 
            Following the course of the moon and sun were the earliest, most
reliable forms of timekeeping. For that reason, calendars were
developed before clocks.
 
       “Coordinated Universal Time” UTC is the standard by which all time
is regulated. All time zones on Earth are based on the system, ranging
from -12:00 UTC to +14:00 UTC.
 
            The academic term for a “leap year” is an intercalary year. This
happens because a true solar year is slightly more than 365 days.
 
            The world’s oldest sundial dates to about 1,500 BCE in Egypt. But
telling time from shadows was the earliest type of timekeeping.
 
       It takes just under 24 hours for the Earth to rotate. The precise time is
23 hours, 56 minutes, and four seconds.
 
            There are actually measures of time less than a second. A Planck
time is the period it takes light to travel one Planck in a vacuum or
5.39×10−44 seconds.
 
            In 2018, a lag in the European power grid caused the clocks on the
continent to be six minutes slow. The problem was resolved after a
few months.
 
            The first mechanical clocks began appearing in Western Europe in
the late 1200s. The earliest clockmakers were German, with the
German and Swiss clockmaking tradition continuing to the present.
 
            “Greenwich Mean Time” GMT, refers to the time at the Royal
Observatory in Greenwich, England. Although it’s commonly thought
to be synonymous with UTC, it’s actually the time zone UTC +0:00.
 
       Rolex was actually founded in London, England in 1905 but moved
its headquarters to the watch/clock capital of Geneva, Switzerland in
1920, where it remains today.
 
            The Greek word for water clock is clepsydra. Water clocks worked
simply by either filling a vessel and draining it slowly and evenly or
filling it slowly and evenly.
 
       Julius Caesar employed the brightest thinkers in the Roman Republic
to create a new calendar that solved the problem of leap year. The
Julian Calendar went into effect on January 1, 45 BCE and lasted until
CE 1582 in most Western countries.
 
       Purely lunar calendars were rare in the pre-modern world. Lunisolar
calendars base their months on the Moon’s cycles but account for leap
years to stay in agreement with the solar calendar.
 
            An atomic clock keeps time by determining the frequency of the
radiation of atoms. Atomic clocks were developed in the 1950s for
commercial use.
 
       Cuckoo clocks originated in the mid-1700s in Germany. They came a
little after the grandfather clock, which was invented by English
