What free things in life actually make you feel like a billionaire?

I always remember the feeling from being a kid and riding in the backseat of my parents car with my head stuck out of the window like the car from Aladdin with the wind blowing through my hair and the sun on my face. It felt like I was the richest kid in the world. So what free things in life make you feel like the richest person in the world?<br><br>Edit: I never thought this post was going to get many replies.
