Certainly one of the best interviews of the series, this interview with epidemiologist and biostatician Knut Wittkowski is hard hitting and touching. We interviewed him on a hot July day in 2020 in a corner of the park and later in front of an empty great lawn, which normally has 1000 people on it in a midsummer day. He is a caring and thoughtful man that is highly alarmed by the turn of events of this last year. He has a tremendous amount of courage to speak out and a big heart. This all comes through.
