Nice video, but the statistics are a bit confusing.

For some of the stats (read: not all), I went to the numbeo.com site (referenced as the source of some of the statistics) and was surprised that all of the "statistics" are not scientifically quantified and are just merely people's opinions with no scientific testing or research of any kind backing up the figures. However, while I watch the video it "feels" like they're backed up by an internationally accredited/approved organization.

Case in point, a personal friend of mine drinks the tap water here, but more importantly, before doing that, he had it tested at a lab in Europe and the results showed that it was 100% safe to drink and meets WHO standards
