In Hindu culture, people greet each other by joining their palms – termed as “Namaskar.” The general reason behind this tradition is that greeting by joining both the palms means respect. However, scientifically speaking, joining both hands ensures joining the tips of all the fingers together; which are denoted to the pressure points of eyes, ears, and mind. Pressing them together is said to activate the pressure points which helps us remember that person for a long time. And, no germs since we don’t make any physical contact!
