Ultrasound can push vaccines into the body without needles (www.newscientist.com)

Vaccines can be delivered through the skin using ultrasound. This method doesn’t damage the skin and eliminates the need for painful needles. To create a needle-free vaccine, Darcy Dunn-Lawless at the University of Oxford and his colleagues mixed vaccine molecules with tiny, cup-shaped proteins. They then applied liquid mixture to the skin of mice and exposed it to ultrasound – like that used for sonograms – for about a minute and a half.

Hilariously enough, it's closer to the other way 'round. Higher frequencies means more bandwidth but they can be blocked easier. Lower frequencies can go farther before being attenuated too much.

One of my friend's friends has a PhD in psychology, but she thinks that nuclear radiation has healing properties and told me to move out of NYC because there was too much 5G everywhere. She still uses a smartphone though, just on a selfie stick on speakerphone 🤣 She also told me that she was afraid of the radio in her car because of the radio waves.

She could at least use wired headphones. Or is it one simple trick to stop people from calling you?

She's just a bit out there, there is no logic in her actions.

That's fucking amazing.

In a way she’s actually not wrong. That’s what radiotherapy is. Focused nuclear radiation to heal cancer.

She doesn't have cancer though, she's perfectly healthy and is an "alternative medicine practitioner". She said she sleeps with a piece of thorium under her pillow.

Regardless of it being used for cancer treatment, nuclear radiation isn't good for the body in any way. Various forms of radiation (not just nuclear) are harmful, like getting too much sun.

Yikes!

I'm convinced that she's just nuts. My friend, who is her friend (how I met this woman), told me that the woman has started "Urine Therapy" and I just said "Jesus fucking Christ... I... I just have nothing to say" because I didn't wanna get into a debate with him about it.
