Anyone else meal prep on Sundays or am I just getting old?

Started doing this thing where I prep 5 lunches on Sunday morning. Grilled some chicken, roasted veggies, made rice in bulk. Takes like 2 hours total and then I don't have to think about lunch all week. My wife thinks I'm insane for spending a whole morning on it but I save like 60 bucks a week not hitting up chipotle every day. Does anyone else do this or is this officially a dad move?
