Today's 10-minute walk is helping you keep the fitness promise you made to yourself

and we'll add another link to your growing fitness chain.

This is one of those mornings where I think I might have underdressed as the seasons are changing and the temperatures are changing and

cooler air comes in.

I actually got a little cold this week and I'm still not used to, oh, so this is what this feels like.

And I'm still dressing like it's summer.

It's not.

It doesn't feel like summer, by the way.

I was thinking, okay, my hoodie and shorts will be fine for today.

And I left the house and was out for a little bit, and I was thinking,

I think I'm going to be a little chillier than I had expected, which is not fun, but it also

does have an advantage.

I don't know about you, but when I'm cold or colder, I tend to move a little faster.

And so that's not a bad thing, increasing the intensity of my walk and the pace of my walk.

Not a bad thing, even if I didn't plan on it, still not a bad thing necessarily.

So in the United States, most of the country is going to undergo the time change tonight,

or technically at 2 a.m. tomorrow morning.

We turn our clocks back, which means, in effect, it'll get darker an hour earlier.

So if you have been used to walking around dinner time, maybe even

after dinner, Ava and I have been doing that for a long time now, as we'll eat dinner and then

we'll go for a walk. And those walks have been in daylight. Lately, they've been in shrinking daylight,

and I suspect that tomorrow's walk is going to be in the dark.
