I wear corrective lenses (used to have glasses; contacts since age ten). Some people are born with 20/20 vision. Some people have a better sense of smell/touch/taste than others. You can improve some sense, somewhat, through practice and work, but some of us just have more developed abilities than others. And, with the vision analogy, we all agree on and understand this point. When it comes to dealing with people and playing sports, instincts play a bigger role than we give credit for because we all place such a high value on determination and work.
Your instincts are your sixth sense.
