As we age, our fingerprint ridges wear out and become more spaced out than before. … It also means that fingerprints may be affected. Fingerprint ridges of aged individuals are not really different from the ones sampled when they were young, but they do become less rigid.

What can affect fingerprints?

Developing latent fingerprints with ninhydrin may be affected by a number of factors such as temperature, humidity, pressure exerted by the fingers/palm on the surface of contact, the time of contact and amount of sweat transferred.

How long do fingerprints last on a gun?

Prior to this study, it was not known how long a latent print would remain on a handgun after submersion in water.
