plus regular walking is incredibly important.

and most people, (not just elderly) are way too sedentary.

even if the food is the typical amusement park junk food, it's probably better than being sedentary at home and driving to fas goods

Walking from the nearest house to Six Flags Magic Mountain takes around at least 50 mins. If you don't believe me, check on maps.

That's 50 mins of no shade, water, bathroom, or other pedestrians. If you get a heatstroke, you have few options. You can call an Uber and hope they are willing to illegally pick you up on the highway, pay for emergency services, or hope a good samaritan helps you out.

This isn't unique to this location, this is just how almost all American amusement parks are. They are located somewhere out of the city for cheaper rent, with the expectation that everyone arrives by car. This is why they are surrounded by highways and have very few walkable paths and entrances on the outside.

You'd have to drive at that age, too.

Faster than cooking? When you cook regularly you figure out quick meals and meals that take some prep. Quick meals are pasta with a sauce that takes less time to make than it takes the pasta to boil, stir fry, even most curries are ready within 30 minutes. Breakfast is quicker, even with toast or fried eggs.

Not saying it's not ingenious what she does, but cooking doesn't have to take a lot of time is all I'm saying.
