And later we'll talk a little bit about the specifics of how cardiovascular exercise benefits your heart.

Little hint, it's through growth of lymphatic vessels.

Did you know that?

Much of the benefit of aerobic exercise for your heart is because of the way that exercise stimulates growth and health of lymphatic vessels, not heart cells directly.

We'll get back to that.

Walking is terrific, cardiovascular exercise.

You know, these days we are all told we need about 150 to 200 minutes of so-called zone two cardio.

People debate whether or not it's better to do high intensity interval training.

Look, I think it's all good.

It's all excellent.

But none of it really is a replacement for just as much movement during the day as possible.

I work a desk job.

I'm mainly researching podcast episodes or doing research.

Back in the days when I was doing experiments in my lab, I was getting up and standing up and moving around a lot.

I've noticed that with each passing year, I'm 50 now, with each passing year, I tend to move a lot less just spontaneously and as a requirement of my life.

So I do more exercise.

But if you move a lot during your day, that's great.

Vacuuming, cleaning.

This is a great thing for your lymphatic system, okay?

This is also an appropriate time to talk about some of the quote unquote kind of goofy practices that you'll see out there.
