My 73 yr old dad has a picking problem. He has ruined two lazy boy chairs from constantly picking at the arm of the chair and actually picks the fabric apart down to the wood. He doesnt know hes doing it. My mom cant sleep with him at night because his fingers are constantly going like hes picking even in his sleep. He is a vietnam vetetan and i think he was exposed to agent orange but not sure . not even sure if that wouldmatter but tjought i would add it.
