Are you aware of the fact that we are all bestowed with 3 types of immunities? One is innate (or, natural) that we are born with. The next type is an adaptive immunity, which develops all through their lives and the last one is passive or borrowed immunity, somewhat similar to mother’s milk for an infant. However, you let your bodies grow weaker and fall victim to external hazards. Just as you plant more trees and rinse your homes to sanitize your surroundings, you require well-timed evacuating and restocking of your inner system too.
