Other comments: Foi, also known as Foe or Mubi River, is one of the two East Kutubuan languages of the Trans-New Guinea family spoken along Lake Kutubu and Mubi River, located in the Southern Highlands Province of Papua New Guinea. Dialects of Foi are Ifigi, Kafa, Kutubu, Mubi. The estimated number of Foi speakers as of 2015 is between 6,000 and 8,000.

Foi adopts the body-part counting system. This feature can also be found in approximately 60 Trans-New Guinea Languages such as Fasu and Oksapmin.
Counting typically begins by touching (and usually bending) the fingers of one hand, moves up the arm to the shoulders and neck, and in some systems, to other parts of the upper body or the head. A central point serves as the half-way point. Once this is reached, the counter continues, touching and bending the corresponding points on the other side until the fingers are reached.  Not sure if they are still using old traditional body tally system or use Tok Pisin numerals now. New data is required.
