Lots is possible, not that much is likely to be. Our potential influence is worrisomely great, but maybe there is just this disbelief or strong shared believe that protects us.

The paths we take are drawn to each other, but we can only follow our own yes, I'd say. Not really change our own, much less those of others. Maybe not at all.

I sometimes get lots of anxiety from the belief that I can greatly influence the autonomous processes in my body, my heart mainly. This increases my heart rate, but I have real influence only within strict parameters, though I think I could potentially, in theory, make my heart stop using my mind.

It's just that the belief just isn't strong enough. Most aren't probably.

Do you understand what I mean? If not, no worries.

The pills do work, even/especially longterm/prophylactically. Your brain needs protection to re-organise. Our brains are naturally toxic.

Edit:
All brains are naturally toxic, ours only more so. Widens the parameters of what we perceive and the control we have, but only a little bit.
