Literally lived on kombini egg sandwiches last trip, saved a ton.

What's the actual worst part for you, the flat taste or just knowing it's not fresh? Is it mostly about the flavor going bad, or does the whole feel of the place change when they do that?

Absolutely! Seeing friends my age already having trouble with simple things really drives it home. My neighbor can't pick up her toddler without her knees hurting because she never stretched after runs. I've started doing five minutes of light stretches before even unloading groceries, and wow what a difference. It feels silly sometimes but future me will be grateful to still bend down for garden weeds without groaning.
