How old were you when you bought your first stethoscope?

I was 30 and my first stethoscope was an orange Littmann Classic II SE. Later I bought a Peil Cardiology 4000. Both were bought at ebay.

I was about 6 years old. My parents got it for me. I think for Christmas. It was because I had a huge passion about learning about the human body! I still have it today!
