Funny story. When I was in college, I had a part time job pushing carts at Home Depot. It evolved from a summer job doing the same in Chicago, which I transferred to Queens, NY when I moved back for school. I learned in Chicago that were not allowed to listen to headphones while working on the lot (not even one earbud in) for some reason 'unless it was for medical reasons'. This restriction made a physical, repetitive job with little mental exercise even more tedious. So when I transferred to the NY Home Depot, I did a little research on hearing disorders and developed a plan... My first day on the job in Queens, I immediately popped a single earbud in my left ear and began pushing carts. The manager informed me that it was not allowed, to which I responded that I had a hearing disorder and the headphone allowed me to communicate with my cochlear implant. Now, 2 minutes of googling would have proven that I was full of shit, but when you pay your managers 12 bucks an hour...well, that's 2 minutes of extra effort that you just aren't going to get out of them. So I got an exemption to wear headphones at work. I always popped one out so that I could hear customers or approaching cars, but I had one in at all times. This was during the time that I was really getting full-steam into homebrewing. During the next two semesters, I binged close to 100% of the Brewing Network's podcasts. The Jamil Show, Brew Strong, and CYBI were especially insightful. Between those and the MANY books I read over the next few years, I developed a great deal of brewing knowledge and opinion. I am now a professional brewer, thanks in part to them. So if you are at all interested in homebrewing I would definitely recommend the Brewing Network podcasts, especially the older ones. I also think Brad Smith puts on a great one on the Beersmith Podcast.
