In a statutory short form
  power of  attorney,  the  language  conferring  general  authority  with
  respect  to  "all  other  matters"  must  be  construed to mean that the

  with  respect  to any and all possible matters and affairs which are not
  enumerated in sections 5-1502A to 5-1502M, inclusive, of this title, and
  which the principal can do through an  agent;  provided,  however,  that
  such  authority  shall  not  include  authorization  for  the  agent  to
  designate a third party to act as agent for the  principal  or  to  make
  medical  or  other  health  care  decisions for the principal, except as
  otherwise provided in subdivision one of section 5-1502K of this title.
