Washing. Soap is a base, used to remove acids and oils from our skin. You might have notice how slippery ammonia or NaOH feels on your skin - all (liquid) bases feel this way.
Eating - food is converted into energy by chemical reaction.
Likewise, breathing - oxygen used to burn the fuel (food) that we consume.
Even sight - light is converted by our retinas, using chemical reactions, to electricity which is sent to our brains.
