So grinders are a com­mu­ni­ty com­mit­ted to rad­i­cal­ly alter­ing the body. And so some­times it’s treat­ments like tran­scra­nial mag­net­ic, or direct cur­rent stim­u­la­tion. It could be through the use of pre­vi­ous­ly untest­ed chem­i­cals like VIP. Often it takes the form of implant­ed devices. All these approach­es come with risks. What I’m going to focus on today is why despite all the risks being tak­en, a grinder hasn’t died yet.
