The main one of the Yellow Heart Association - Lisbon Delegation is to reduce Loneliness and/or Isolation among the elderly population (or people of working age who, for health reasons, have been left in a situation of loneliness and/or isolation). In proximity or company volunteering, a user is assigned to the volunteer and he makes a weekly visit between 1 and 2 hours. This visit can be at home, it can be a walk, a trip to the café, etc. The match is carried out based on common interests and personality type.
