Do you think I'm too old to buy Buzz Lightyear toy from Toy Story?

I will be turn 20 at two more weeks on my next birthday. When I was about six years old, I started to watch Toy Story on Disney channel. When I loved that movie, my mom bought VHS from some stores to watch this often. When I was about eight years old, my family watched Toy Story 2 in the theater that Buzz Lightyear was my favorite character from all Toy Story films. On my ninth birthday, I had a birthday cake with a picture of Buzz Lightyear and when on my tenth birthday, I had a birthday cake with a picture of Woody. I also had old Buzz Lightyear toy from some stores when I was about nine years old. But when I was about 14 years old, I cleaned out my room that I threw that Buzz toy away in the basement and that my mom sold this to yard sale. On June 2010, my family watched Toy Story 3 in the theaters and Buzz was still my favorite character. Now, I start think about I want to have Buzz Lightyear toy with 12 inches that I can't buy this because I'm too old but I have a good memory to play with this when I was a kid that my Buzz toy had been sold to the yard sale that when I couldn't find in our basement. Do you think I'm too old to buy Buzz toy that I just take many pictures of this?
