Due to the high cost, the majority of the estimated 300,000 people who received implants in the world are in developed countries.
Very few percentage of people in developed countries are able to afford the cost of implants as majority. Most of the earnings of people in developed countries are spent on basic necessities of life like food, clothing and shelter.
Underdeveloped countries have people with income issues they will have the less amount of money.
High cost and majority of implanting were done in under developed countries is absurd because as said earlier underdeveloped countries cannot afford costly treatments.
But still it varies from person to person. Not every healthy emotional person grow trust between one another. Some just rush towards friendship for their own purpose. So it depends!
