Are Sneakers and Sports Bras Necessary?

Today I went on a bike ride around the cute neighborhood across the street from my house. Now before you get a picture in your head of me wearing a pair of fancy sneakers, exercise shorts, and a sports bra while hunched over my handlebars and grunting, I guess I should clear a few things up.

I am not serious when it comes to exercise.

I tend to forgo the proper shoes and just wear flip flops. I ride around leisurely (not huffing and puffing) noticing the squirrels with acorns in their cheeks, the men repairing dilapidated roofs, and the shapes of clouds. I listen to the music on my phone, but I don't wear earbuds--I just let whomever is around me hear what I'm hearing.

I'm sure in comparison to the other folks in the neighborhood, I look like I'm 12 years old and like I don't take my "workout" time seriously. Everyone else I saw today was wearing an actual workout outfit, actual Nikes, and a stern expression--like if he or she didn't burn the proper amount of calories, life simply would not go on. Me, I looked like I was just pondering a Wednesday afternoon, one hand on the handlebar of my beach cruiser and the other reaching out to grab the breeze.

Does this count as exercise? I'm sweaty as I type this, and I feel relaxed. It definitely counts. So why does everyone else act so serious about a simple walk, jog, or ride? Am I just weird for watching the squirrels?

Or are they weird for ignoring them?
