Fortunately I was preparing for Thai hitmen to come so I am prepared. I may have to change my sleep schedule though.
Sounds like you are living in a not so safe neighborhood.... Of course, one of the things that any of us needs to consider is the condition of the neighborhood in which we live, and whether it would be better to get more security, merely by feeling more comfortable with the values and culture of the neighbors.
Sometimes traveling in a country outside of your own will put you more into those kinds of safety, security, health dilemmas.. but sometimes also NOT understanding the safety (or lack thereof) of a location until you have lived in such lcoation for a bit of time.
Seems that older people are less tolerant to taking such risks, too, but older people do not tend to move locations as often, either.
