EXCERPT All ages are NOT equal in fingerprinting. Where fingerprinting is especially vulnerable is on the extreme poles of the age groupings. Children and the elderly have special problems in fingerprints not found in the age groups in between them.
CHILDREN: children's fingerprints are more short-lived than adult fingerprints. Children's fingers do not yet contain the more waxy oils that become present at the onset of puberty. These lighter fatty acids of children's fingerprints evaporate within just a few hours.
ELDERLY: Aging causes us to lose fingerprints. Older people are having difficulty using biometric identification technology because their skin is thinner and the ridges on the fingers not as pronounced. Additionally, the more years we spent doing certain repetitive tasks, the likelier it is that we are wearing off certain fingerprints. Chief among these are the fingers one uses on one’s computer devices. So a person who is now a senior citizen, who has been avidly using every computer contraption and device for decades, is likely to be missing a few fingerprints. The exact fingers are the ones you use on each hand to hit: q,w,a,s and o,p,l, and ;.
