Fantastic point. I'm blessed with fairly simple tastes when it comes to food, and I'm fine with some of my meals being fairly bland (pasta salad, for example, or spinach salads). But when it's easy and healthy, there's no reason not to make the food taste better.

Sidenote: the longevity article points out that garlic is linked to longer lifespans. So seasoning with garlic both increases flavor and health.
