I've come to a conclusion.
I don't need to go for a run right now.
I have a 5yr,3yr, and 6 month old.
I have a foot of snow to shovel in a huge yard, ice that took me 30 mins to scrape off, AND huge logs to lug into the outdoor furnace...did I mention that I need to haul the huge logs into a wheelbarrow and maneuvre the wheelbarrow in the foot of snow 70 feet ???
Yup...I don't need to go for a run right now.
