Do this now, before you forget.
Open your phone and enter a contact named ICE. This stands for In Case of Emergency. Put a number to call associated with this new entry.
Also go in and enter mother, brother, sister, father, etc before the contact entries of their actual names (if you don’t do this already).
That way if something should happen to you it makes it easy for help to identify you and contact next or kin or emergency contacts.
Do it. It could save your life.
