Input: Consider Input: A callus is an area of thickened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on feet because of frequent walking and incorrectly fitting footwear. While they can be perceived as being unsightly, calluses are generally not harmful, but if neglected for long periods may sometimes lead to other problems, such as a skin ulceration or infection, or cause the sufferer to try and offload the affected painful area, which can place excessive stress on the asymptomatic side. Rubbing that is too frequent or forceful will cause blisters as opposed to calluses to form.

Output: why do i have callus on my hands

Input: Consider Input: In the United States, Congress has not attempted to enact any nationwide federal smoking ban. Therefore, smoking bans in the United States are entirely a product of state and local criminal and occupational safety and health laws. As a result, the existence and aggressiveness of smoking bans varies widely throughout the United States, ranging from total bans (even outdoors), to no regulation of smoking at all. Jurisdictions in the greater South tend to have the least restrictive smoking bans or no statewide bans at all. Of the 60 most populated cities in the United States, all but 17 ban smoking in all bars and restaurants.

Output: when was smoking banned in hospitals in usa
