I was walking through Old City, Philadelphia on Sunday afternoon when I looked down at my Apple Watch and saw that it was 98 degrees. It felt hot, but not that hot. Yesterday’s high in Philadelphia was 99 degrees, and today’s is expected to be 95 degrees—getting better as the week continues.

If you don’t enjoy this sort of heat (I do) it can be brutal. But I think it can be useful, at least in terms of reminding people to literally sit down and relax. We don’t do enough of that in a culture that’s more frenetic than it needs to be.

Growing up without climate control, I remember spending long mornings and afternoons in the heat, in a sort of suspended animation on the porch or under the shade of the giant birch or oak trees, or finding a hose someplace or making lemonade. And more than that, I remember specific experiences of those sweltering summer days more readily than I can recall other kid moments from other seasons.

Heading to Washington tomorrow for Independence Day, and spending the rest of the week there before flying to Seattle on Saturday evening.
