Agreed. The primary concern is tissue heating that cannot be sufficiently dissipated. This is nearly impossible at "wifi" power levels(Below 1 watt) without car

Agreed. The primary concern is tissue heating that cannot be sufficiently dissipated. This is nearly impossible at "wifi" power levels(Below 1 watt) without carefully contrived situations -- such as placing your eyeball(which is the least-equipped organ to dissipate heat) at the exact focal point of a specially designed parabolic dish. I have been safely working around thousands of watts of RF power for 20+ years and have maintained my 20/15 vision.
