3.Taste receptors are located in the heart
Some taste buds are only present at toddler level and they disappear with age. Fully grown adults have 10,000 receptors in their mouth and as age progresses, they decrease so much so that they have been cut into half by the time we are 60. The amazing thing is, receptors of sourness are located in the heart to recognize infections.
