Celebrity Gossip Graph (Abel Acuña)

The above graph displays interest in celebrity gossip in relation to gender and age. Some questions to consider include:

1) Were there equal numbers of participants surveyed from all age groups? The very old and the very young appear to be lacking in numbers.

2) Is this the best fit? Are we born with an interest in celebrity gossip? Perhaps a Gaussian curve suits best, but it seems that not enough data has been gathered.
