The baseline for the populationâs percentage of left-handed people is around 10 percent, but in some societies that number is far greater. Among Venezuelaâs Yanomami tribe, about 5 in every 1,000 people are murdered yearlyâand about 23 percent of the population is left-handed.

And then there are the people of Jimi Valley in Papua New Guinea, who have a murder rate of 5.4 in 1,000 and an above-average instance of left-handed people at 13 percent.
An ejection fraction of 60% means that 60% of the total amount of blood in the left ventricle is pushed out with each heartbeat. What's normal? A normal heart's ejection fraction may be between 50% and 70%. You can have a normal ejection fraction reading and still have heart failure (called HFpEF or heart failure with preserved ejection fraction).
