If you are really considering this, I recommend that you first see if you can volunteer a bit at a local bakery. I also was considering a career change to becoming a baker. I knew someone who worked at a fairly large yet still artisan bakery (their brick oven was built by some specialists who came from France). He let me come work for a day to see what it's like. I quickly realized that as much as I love bread, I'd get bored doing relatively the same thing every day. I think that it's also a life where you can't easily take time off, which depending on your current situation in tech may not be much of a difference. :)
