Quality of Life in Phnom Penh, Cambodia

For the past 15 years I've spent half my time in Phnom Penh each year. I've found Phnom Penh to be an extremely safe place both day and night. Of course there is pretty thief, but being stupid doesn't help. Medical care unfortunately is not good (it's bad) as getting really sick requires a trip to Bangkok, Singapore or Vietnam.
Dental care is a completely different story. Dental care is just outstanding, there are so many excellent dentists with prices from 50 to 80% cheaper than the US. There are a few that are not so good, but just ask any expats that have been there a while and they can easily recommend several good dentists. On the subject of pollution I'm not sure how Numbeo arrives at their index, but I find the air quality excellent throughout the country. Cambodia being a poor country, there's a need to help people, which often gets labeled as corruption. The police get about $200 per month, so it help to tip them if you need assistance. I see nothing wrong with this. Retirement visas are easily gotten if you're over 50, any travel agent can help with this.
