There’s something coming this summer called SMART UNDERWEAR!
They have sensors that read your body stats. Like heart rate, temperature, etc.
These undies interact with smart devices in your house. So, if you’re hot, they’ll tell your Nest thermostat to lower the temp. If you are stressed, they will tell spotify to play music to calm you down.
Not cheap… 4 pair start at $279!
