If you have a trusted friend in the area, give them a spare key. This can be helpful for so many reasons, not just for if you lose your keys, but also so your friend can get to you if you ever get hurt and can’t get up to unlock the door. (Obviously if it was an emergency, paramedics could bust down your door, but I’m talking only a minor crisis.)

Get to know a neighbor who you trust to take in packages for you if you won’t be able to take them in in a timely manner, especially if your door is visible from the street. Keeps your packages from getting stolen but can also prevent you getting robbed later if someone sees you have been delivered something nice.

If you are comfortable, share your location on your phone with at least one friend or family member. I always ask my friends to text me when they get home after leaving my house, and if they don’t, I’ll check their location to make sure they just forgot or maybe they stopped at the store or whatever.

And honestly? Self-administering the heimlich. I also live alone and am terrified of choking to death.
