William B. Bean studied his own nail growth for 35 years and published 
the data in Arch Intern Med, 1974, Vol. 134, 497-502 (30 yrs) and ibid, 
1980, Vol. 140, p. 73-76 (35 yrs).  He found that nails grow more slowly 
with age; growth rate at age 32 was 0.123mm/day, but by age 67 had decreased 
to0.095mm/day.  No variation with geographical location, physical activity, 
or season.

So, in one year that is 365.4 x .123 mm = 44.9 mm, or 4.5 centimeters.  Hmm.  I 
think mine grow more than that...
