how fast do nails grow?

Enter the experts, please...
How long does it take nails to grow? And, how much faster do they grow on the fingers? The old "rules of thumb" were:

• Fingernails: 6-8 months to grow out fully Thumbnails 8-12 months to grow out fully
• Small toenails 12 months to grow out fully
• Great toenails 12-18 months to grow out fully

Mr. 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.

Thumb nails grow faster then the rest of the fingernails. Great toe nails grow faster then other toenails. Toe nails grow slower then fingernails. Umm.... Just like you thought!
