There are lots of funny and innovative ways in which we can live. For example, we can rent an apartment, rent a room, live in the house, build a house, create a tiny home, build a tough shed from Home Depot for only $4000, live out of our car, live in a sprinter van etc.

For example, can you live out of a Prius? Or a Tesla?

In terms of showering, very easy. Just have a gym membership at the local commercial gym.

I think the more practical and pragmatic one is in regards to food, food disposal, garbage etc. Also having a good washer and dryer.

Also, in regards to cooking. Having some sort of sink, cooking set up, refrigerator etc.
