HOBBIT AGE CONVERSION CHART
Some while back there was a discussion on one of the E-lists about the differences in maturity of Hobbits as compared to Men. JRRT seems to hint that the difference is approximately two-thirds. When reading what he has to say about faunts in Letter #214, and comparing the Coming of Age of Hobbits at thirty-three with that of humans at twenty-one, it seems to bear this out. During the discussion, Topaz Took came up with a formula that actually works the difference out at .64.
Using a calculator, I came up with the following chart. I have rounded the ages up or down to the nearest half-year for simplicity's sake. This is, of course, only for comparable physical ages, and does not take into account the possibilities of mental, social and cultural differences.
I fully realize that not everyone agrees with this ratio. A number of people believe that there is not a physical difference, and that Hobbits simply make their young people wait longer for the responsibilities of Coming of Age. Others believe that Hobbits grow the same as humans until they reach their tweens, when they then have an extended adolescence. Others believe that the ratio holds true up until Coming of Age, when it then begins to gradually fade. However, for those who do agree, I hope this Chart will prove a useful tool.
