There is a cool #biohack for human males. If you are feeling cold, but your balls are not tightened up to your body, you have a fever. The temperature control for your little swimmers is independent of the rest of your body, so while your body needs to heat up to fight whatever is coming, your balls will be just chilling out.

Me personally, I have one more thing. If something is coming up, I don't need costly smartwatches that can warn me in advance (yeah that's a thing!), I just stop being horny all the time.

And I am not horny right now... sigh.
