<human>: Here is a goal: How do you inflate your bike tires?

Which way makes more sense to accomplish this goal?

OPTIONS:
- You can open the bike tire nozzle, put it in your mouth and blow air in until the tire is hard.
- You can plug a bike pump into the nozzle of the bike tire and pump air in until the tire is hard.
