If you are stressed about the bear market, you would benefit from the stimulation of the vagus nerve. I made an open-source desktop and Android sw to control the device, so you don't have to sign-up, get locked out when the server or your connection is off. It is easy, now with better UI and works better on background (but for Android, still keep it in the foreground, but it would not stop the stimulation now).

Vagus nerve stimulation is one of the best longevity hacks, helps your body heal by reducing chronic stress.
