Most of us can relate the aging process to the visual changes we observe. We might not move as quickly and we are not as stable on our feet.
What about the aging process when it comes to our senses (hearing, vision, taste, smell, touch)? These are often more gradual and less noticeable changes.
Our senses collect and turn information into sensations that our brain interprets. A certain level of stimulation is required before a sensation is created, often referred to as a threshold. With aging, the threshold is raised requiring more stimulation to create a sensation.
