THE MANDOI (or Mandi) were a short-lived tribe of Indians who grew old and wrinkled almost as soon as they were born.

Mandi was a historical kingdom located in the foothills of the Himalayas.

Pliny the Elder, Natural History 7. 24 (trans. Rackham) (Roman encyclopedia C1st A.D.) :
"Ctesias [Greek historian C5th B.C.] writes that also among a certain race of India the women bear children only once in their life time, and that the children begin to turn grey directly after birth." [N.B. "to turn grey" in Greek meant to become old and wrinked.]

Pliny the Elder, Natural History 7. 28 :
"Crates of Pergamenus [Greek scholar C2nd B.C.] tells of Indians who . . . do not exceed forty years, this tribe adjoining the Macrobi (Long-Livers), whose women bear children only once. Agatharchides records this as well, and also that they live on locusts, and are very swift-footed. Clitarchus [Greek historian C3rd B.C.] gave them the name of Mandi; and Megasthenes [Greek historian C4th B.C.] also assigns them three hundred village, and says that the women bear children at age of seven and old age comes at forty."
