Here is a tip from Natural Solutions magazine April, 2008, p. 42. “Anyone who has to use a fine touch in their profession should keep his or her nails trimmed to avoid injury….This includes….those who do a lot of typing or piano playing. The constant banging of the nails against the keys can cause small hemorrhages, which appear as purplish splinter-like streaks….Over time, it can even lift the nail from the nail bed.”
