1. You’re taller in the morning and shorter at night.
This is an interesting natural phenomena that happens with all our bodies. Every night, when we go to sleep, we all get a little bit taller, and as the day goes on, we all get a little shorter. Even though it seems like a complex process, it is rather simple. The process starts in the vertebral column, specifically in what is known as the nucleus pulposus, or the inner part of the vertebral disc. A gelatin-like material provides cushioning and protection to the spine and as you walk, run and perform other activities. This gelatin-like substance acts as a shock absorber and eventually becomes compressed.
When you rest during the day, it rejuvenates and expands back to its original form. The passive process called imbibition takes place at night or when there’s no load on your spine. The process is repetitive and takes place throughout our lifetime. (

2. The heart imitates the music that we listen to.
Studies show that there’s a connection between our heart and the music we listen to. A series of studies shows that various tempos can influence exercise, anxiety, post-surgical recovery, and many other outcomes. Typically, a heart beats around 60 to 100 beats per minute, depending on the individual and their lifestyle. The heart rates of athletes can be higher than 100. Coincidentally or not, most songs have 60 and 200 beats per minute.
Massive 2016 hits such as Calvin Harris and Rihanna’s “This Is What You Came For” (124 bpm), Galantis’ “No Money” (126), Nick Jonas’ “Close” (124), and Lukas Graham’s “7 Years” (120) were at the top of the charts. A 2002 study found that we do have a preferred tempo, which is between 120 to 130 bpm range. Depending on our activity, we tend to select music that matches our tempo. For instance, when working out, the average person’s heart rate is around 160 bpm to 190 bpm, which is also similar with Kent Jones’ “Don’t Mind” (159 bpm) and Alan Walker’s “Sing Me to Sleep” (176 bpm).

3. Like our fingerprint, our ears and tongue prints are unique with each individual. No other person in the world has the same ear curves and ridges or tongue prints as yours.
Yes, it’s true. You’re one in 7.5 billion. It’s not just your fingerprints that are unique. Like your fingerprints, the ridges of your ears as well as the shape and texture of your tongue is unique. No other person in the world can match your combination. In one British study, scientists were able to develop an algorithm that was capable of identifying a single individual out of more than 250 others with a 99.6% accuracy rate by analyzing how light reflects off the curves of the ears. In fact, the ridges in one’s ears are so unique that Yahoo is planning on developing a technology that unlocks smartphones with the help of an ear scanner. With this technology, users are able to set up their smartphones in such a way that calls can only be answered when they press the phone to their ear; thus unlocking the phone and accepting calls.
Like your fingerprint and ears, your tongue is also unique. The shape, texture, tiny bumps and ridges are unique with each individual. Since they rarely get damaged or altered unlike our fingers that can become scarred, scientists are developing a 3-D tongue imaging to aid in identification. (

4. The acid in our stomach is so strong that it can dissolve metal.
This stomach acid (also known as hydrochloric acid, or HCL) needs to be strong enough to turn whatever we just ate into a liquid mush. Also called gastric acid or gastric juice, this acid helps us digest the food we eat. The acid is highly concentrated so our stomach renovates its inner layer every 3-4 days in order to protect itself. Studies show that the strength of the acid is powerful enough to dissolve metal objects (we don’t recommend testing that out).
If the stomach acid is not strong enough and allows undigested food to pass through, then the body’s balance is disrupted. The acid also plays an important role in protecting us from bacteria that may be on ingested food. (
