10 Fun Facts You Didn’t Know About Life
1. Life expectancy is increasing
The average life expectancy is steadily increasing. In 1950, the average life expectancy was 68, while in 2020 it is projected to rise to 78.7 years. This increase is largely attributed to medical advances, although improvements in the areas of nutrition, education and lifestyle have also contributed.
2. Humans blink twice as much as other animals
Humans typically blink twice as much as other animals. According to one study, humans blink an average of 13 to 15 times per minute. This is more than twice the rate of other animals, which generally blink between 6 to 8 times per minute. This is thought to be due to the fact that humans are more prone to eye fatigue as a result of our increasingly digital lifestyles.
3. We only use 10 percent of our brains
Contrary to popular belief, we actually use much more than 10 percent of our brains. Recent research suggests that humans use almost the entire brain for various functions. This means that we don’t have “unused portions” of our brains that are waiting to be tapped into.
4. The average human heart beats 100,000 times a day
The average human heart beats approximately 100,000 times per day. This rate can be affected by age, physical activity, and other factors. The heartbeat is typically measured in beats per minute (BPM), but in general, an adult heart will beat an average of 60 to 100 BPM.
5. Humans have more bones in their bodies than other animals
Humans typically have 206 bones in their bodies, while other animals typically have fewer. This difference is due to the fact that many of the bones in the human body are fused together, while other animals have more separated bones.
6. The human tongue is the strongest muscle in the body
The human tongue is surprisingly the strongest muscle in the body. This is due to its unique ability to move in many directions and its muscular construction. The tongue is composed of eight muscles, which allow us to manipulate food in the mouth, speak, and even swallow.
7. An adult human body is made up of approx. 7 octillion atoms
An adult human body is composed of approximately 7 octillion atoms. This is equal to 7,000,000,000,000,000,000,000,000 atoms. This number is so large, it’s almost impossible to comprehend.
8. There are more deaths per year from selfies than shark attacks
It may be surprising to learn, but it’s true – there are more deaths per year from selfies than from shark attacks. According to the Journal of Family Medicine and Primary Care, at least 259 people died taking selfies between October 2011 and November 2017. This number is still growing.
9. The human body has enough iron to make a 3-inch nail
The average human body contains enough iron to make a 3-inch nail. Approximately 0.006 percent of the body is composed of iron and this is enough to create a small nail. Iron is vital to the body, because it helps to create the protein hemoglobin, which carries oxygen throughout the body.
10. The human body temperature varies during the day
The human body temperature varies throughout the day. Generally speaking, it is lowest in the morning and highest in the late afternoon. This fluctuation is due to the body’s internal clock, which changes its temperature based on circadian rhythms.
There are many fascinating facts about the human body and life in general that we may not be aware of. From the power of the tongue to the amount of iron in the body, it is clear that the human body is an amazing and complex organism.
