This is just a superstitious statement. Don't take it seriously Your destiny is in your own hands. Don't believe anything unscientific. Some people are lucky in life, but they are lucky. Don't envy them or envy them. Our own destiny still depends on ourselves, and we can't rest on our laurels just because of a superstitious remark. Destiny is created by ourselves.
The low hairline at the back of the neck is just a physiological phenomenon, which has nothing to do with fate. Don't believe in superstition, believe that your destiny is in your own hands, and decide what kind of life you want.
