So I have a treadmill now, despite a horrific accident roughly four years ago that resulted in my brother-in-law saving my life as I sped backward, and an awkward entanglement of limbs at family Christmas. This treadmill is much less devious than that one, and since we've now established a relationship that doesn't require me casting a suspicious eye on it as I run, I'm free to indulge in listening to an audiobook, or... a podcast.
I found a great series - Meet the Author - on iTunes free podcasts. There are some big names on there, in nice little one-sitting interviews that you can tune into while exercising, walking the dog, or lying comatose on your couch (as long as you prefer your comatose periods to be short lived). It's free advice from people who know what they're doing - check it out!
