*when the sun is the highest in the sky. Shirt off, if you dare. Start slow (don't be stupid and burn yourself).

The energy is incredible. I walked about 20 miles this morning with the sun coming up before biking 6 miles to work and then back in the evening. And I know I'll have lots of energy to spare tonight.

Yes we are warm blooded animals but still very dependent on the sun and activity.

20 miles is just 6 miles less than a marathon, and would take over 6 hours at the normal pace of 5 km/h. Is that really what you manage to do in the morning before work? :-O

Thank you for catching me. No, that is not what I walked :)

So, um, was that a typo? Am I parsing your sentence wrong? Been waiting for an edit but it doesn't seem one is coming. :-)
