We’re all quite familiar with having five senses: sight, touch, taste, smell, and hearing. These senses help us understand the world outside our body. The idea of five senses is so ingrained that having a ‘sixth sense’ is a clue that something isn’t right. But what about other physical sensations?

Baby boomers are retiring and improved health care has extended life expectancy.
