Plantar warts often develop beneath pressure points in your feet, such as the heels or balls of your feet. Most plantar warts aren't a serious health concern, but they may be bothersome or painful, and they can be resistant to treatment. You may need to see your Podiatrist to treat and remove plantar warts.
My formal (but open to improvement) definition of 'science': A science is a method, a set of rules using fact and logic, for evidence gathering and testing truth claims in a given field of inquiry, rules which are publicly usable (i.e., neutrally applied to all participants), and which can reasonably be said to lead to the truth of that particular area.
Main article: History of science. Science in a broad sense existed before the modern era and in many historical civilizations. Modern science is distinct in its approach and successful in its results, so it now defines what science is in the strictest sense of the term. Science in its original sense was a word for a type of knowledge rather than a specialized word for the pursuit of such knowledge.
