No, I do not wear or buy leather, nor fur (obviously), wool, any other animal hides, or silk. Additionally, I won't buy or use items containing animal products, and as much as possible, avoid any products that were tested on animals. Because animal products are practically everywhere, it's hard to avoid anything that hasn't exploited them directly or indirectly. But Veganism is becoming quite widespread and there are more cruelty-free alternatives than ever now.
I've been vegan for 7 years now; prior to that I was mostly vegetarian, other than the once-in-a-while trip to the sushi bar, etc. No one enjoyed a steak more than I did. It's an ethical choice for me and because of that, I don't 'miss' my prior diet at all.
