How could you flex your workday to work with nature?

I started my day yesterday with an early morning bike ride

Two days ago, as it has been for nearly a week, the temperature where I live crept up to nearly 30c (88f), with not a breath of wind and very high humidity. Ok, so 30c in cayman is an average day, and I never suffered in the heat there for decades, but hey, Cayman has air conditioning and fans. London?. Nope. Now, as my working day went on, I knew I’d booked myself into a group bike ride for 6:30…
