you've never walked under a high voltage power line? even driving a car under it you can hear the radio being weird. i assume it can make life miserable for a ham radio enthusiast. also, walking beneath one, you can hear the crackle, which is why nobody places a power line above homes.

as for them causing leukemia i'd not consider that realistic

My home is like 1500 ft from HV lines. According to OSM, they are 115kV. Some of my neighbors are even closer. These things are totally built near homes.
