Amazonian tribe has no concept of time or dates
Professor Chris Sinha, of the University of Portsmouth, led the research which found that the Amondawa people of Brazil do not even have words for ātimeā, āweekā, āmonthā or āyearā.
In his study, published in the journal Language and Cognition, he argues it is the first time scientists have been able to prove time is not a deeply entrenched universal human concept, as previously thought.
