Is it like being at home in meal preparation or does the facility do it? What things are mandatory? I'm 54, are there others my age?

What exactly are you asking?

OP has another question going.

Are you being offered a new place in an Assisted Living Facility, and trying to decide if it's the right move for you?

Quite a lot must depend on where you're living now, if you're going to compare the two options. Is your rehab ongoing?
