The problem that needs a solution is hygiene problems and contracting a lot of diseases from touching metal surfaces such as hand railings, metal buttons and door handles.
My solution is to make a keyring that has a hook and a stick on the end of it so you can pull open and close doors, and the stick is to click buttons, this solves hygiene problems. The software I used was invented, this is a 3D printing software.
