As it is, the poll reveals the life of a coin collector:
Under 12, parents and grandparents have instilled an interest in coins.
12-15, interest in coins continues to grow.
15-18, interest lags as sports and puberty are more important.
18-25, part time jobs allow collector to rev up hobby.
25-35, full time jobs and striking out on ones own still allows time to collect.
At least, until marriage, a home and kids slow things down.
35-50, college costs slow things down.
50-65, kids are gone and marriage is routine, TV is lousy and coins are rediscovered.
65+, time to buy the coins that one has always wanted!
Sound about right?
