I only have a very few memories with some kind of story before I was one year old. The most memories from then were more like snapshots. I have storyline memories from about 2-3 years old and onwards.

I also took the quiz that was linked from that page, you have 15 words. They say it is normal to have a memory bump in your teens. My result:

0-10: 8 memories (5 being ages 2 to 7)
11-20: 3 memories
21-30 4 memories

I feel abnormal.
