There has to be a metaphor in there somewhere. About becoming so weak that burdens one used to bear easily become almost unbearable. And the solution is to become stronger or lose some of that luggage, or both.
Yes! So true! I'm noticing this with myself, too. I'm desperate to feel physically stronger because I'm noticing I'm feeling emotionally, spiritually and mentally stronger. It's amazing how they are all linked.
Keep on running. It's a great place to think, right?
