Life is not a computer you can hack. I bet we barely understand 1% of how our system works and trying to hack it means one is not even aware of their ignorance.
All of those also screw up your sleep something fierce, and so (general you) end up piling hacks on top of hacks to make something kinda sorta work that you understand less than you did the original system.
(Although, PSA, I do understand that the vast majority of people whose sleep is ruined by alcohol or caffeine or both are also too addicted to quit, and this isn't at this point a conscious attempt at "hacking" anything.)
Oh, if one sees the enormity of complexity body & mind has - one can be sure he can not foresee all side effects. I like that you gave examples like caffeine which messes up your nervous system or alcohol which destroys your conscious attention and lever, among other things :)
Well I also did not say it's permanent. Messing up can be temporal but it also builds up and becomes harder to get off. Temporal should not be taken lightly.
And I like how you passed up the other examples. Are you also advocating against medical drugs or vaccines? They fit the "hack your body" description to a tee.
I used the ones which have clear undesirable side effects, others might have it as well just that we don't know about them.
>Are you also advocating against medical drugs or vaccines?
I am only advocating about being conscious of how much we don't know. If medical drug or vaccine saves lives - I have no problem with it, still most likely we don't know all the side effects.
