The sidewinder snake can pick up things at night by the heat that they deliver, but we don't have that ability.

So in general, it's not harmful to have some degree of heat landing on you.

And there are some infrared cameras that are used in the dark for the military where they actually send out an infrared beam

and then just pick up the heat coming back.

So it's just like sending out light except your eyes won't detect it so you, the enemy, are not aware that you're being scanned.

And if they're sending out heat, it's not harmful unless it causes burns.

Is that what you're worried about?

And tell me about what they did for your orthotics.

I don't understand that one.

That's new to me.

Wow.

Okay, so first thing is that all the cameras on the phones pick up infrared.

It just turns out that the technology that we use picks up infrared and visible, and you can prove this by getting a remote control for a TV, one that puts out an infrared beam, and then aim it at the camera on your phone.

and then press a button and your eyes will not see a single thing, but the sensor on your camera will pick up the infrared and you'll suddenly see the front of your remote control for your TV putting out a little blip of light.

Wow.

So most cameras can pick up infrared.

So I don't think it's harmful and good on you for getting the orthotics.

Have you had a bit of, what, plantar fasciitis or something like that?

Oh, that's such a good outcome.

Hooray for modern technology helping you.
