Too many health issues as one gets older and these are treated free at home. The older you get the the more you pay for insurance, or are refused. It doesn't take me long to get tired of the heat, the food, the ladies and the broken or non existent footpaths, not in any particular order. Once I start losing tolerance on any given day it's time for me to go home , usually a month at a time is good but now with the expensive flights it's looking like less time in LOS .
