* Stress levels are generally lower in Spain, IMO - broadly speaking, people don't seem to work as hard as they do in the US. There are obviously pros and cons to that, but one pro is that life is generally more easy going, people aren't always in a hurry, they take time to enjoy the moment (like good food with family and friends) frequently. This translates into looking and feeling younger. I was once driving in my village and traffic was backed up. I couldn't figure out why on this little street no cars were moving, but I saw a man getting a drink from a drinking fountain in the park next to the street. He waved at everyone and got back in his car and we all started moving again. No one honked, no one was angry, people waved back and we moved along. It was a stark contrast to how that would have gone in the US.

* High quality food is pretty affordable and the EU does reduce a bunch of junk that we allow in our foods. For instance, most US bread is loaded with preservatives. In Spain, most bread is freshly baked and acquired more frequently instead of buying mega amounts at Costco (that then require preservatives). There's also not a drive-thru soda store every few blocks! Also, the Mediterranean diet is largely pretty prevalent. More fish, olives, nuts, etc - but they do love their ham! Spain has the best olive oil I've ever tasted in my life.

* In general, cars are less prevalent and you don't need to drive everywhere. For instance, in my village in Spain, I could walk from my house down to the local grocery store to pick up a fresh loaf of bread and other sundries, get a haircut, etc. without hopping in my car. It takes longer, but again, when time is not as scarce, that's not a big deal. Mass transit is really good, so busses and trains make getting around without a car very reasonable. This in turn leads to more walking, which is generally good for health.
