The sign of lung diseases shows up at the tip of the index finger. When you straighten the index finger horizontally, if the tip of the nail is lower than the first joint from the tip of the finger (Distal Interphalangeal Joint (DIP)), there is a high possibility of having lung diseases (Fig. 1).
Hardening of the arteries (arteriosclerosis)
Hardening of the arteries is the condition, which is caused by unhealthy lifestyle such as lack of exercise, unbalanced diet and smoking, that LDL cholesterol attaches on the wall of the artery, narrowing the artery and stopping the blood flow. Leaving hardening of the arteries as it is, it leads to heart attack or stroke.
But looking at the ear can distinguish whether you have hardening of the arteries or not.
How to check whether to have hardening of the arteries by looking at the ear
A Normal person’s ear doesn’t have any wrinkles (Fig. 2), but the ear of a person with hardening of the arteries has wrinkles in the ear lobe (Fig. 3).
There are various types of wrinkles as shown in Fig. 4.
According to a research in University of Chicago, within 376 people who had heart attack, 275 people (73 %) had wrinkles in the ear.
Why do wrinkles appear in the ear?
The ear lobe has few blood vessels (Fig. 5). Hardening of the arteries causes poor blood flow of all the body, nutrition is not delivered to the ear lobe and the fat in the ear withers, causing wrinkles.
How to check whether to have hardening of the arteries in the brain
(1) Hold your nose with your left hand (Fig. 6).
(2) Hold your left ear with your right hand (Fig. 7).
(3) Replace your left hand by your right hand (Fig. 8).
(4) Repeat (1)-(3) for more than 10 times within 10 seconds.
If you can’t do this more than 10 times within 10 seconds, there is a possibility that the blood vessels in your brain have hardening of the arteries. If you leave it as it is, there is also a risk of developing stroke.
When the blood flow in the brain is poor due to hardening of the arteries, it is difficult to transmit the order from the brain and that makes difficult to do fine movements.
If you can with training, you don’t need to worry because people with hardening of the arteries in the brain can’t do this no matter how many times they try.
