Not OP, but several examples:

A. instead of building a house on random terrain with random materials, first we prefer to flatten the place, then we use standard materials (e.g. bricks), which were produced from simple source (e.g. large and relatively homogenous deposit of clay).

B. For mental tasks it’s usual to said, that a person can handle only 7 items at a time (if you disagree multiply by 2-3). But when you ride a bike you process more inputs at the same time (you hear a car behind you, you see person on the right, you feel your balance, you anticipate your direction, if you feel strong wind or sun on your face you probably squint your eyes, you take a breath of air. On top of that all the processes of your body adjust and support your riding: heart, liver, stomach…)

C. “Spherical cows” in physics. (Google this if needed)
