There's a couple ways to read that, one being 'at dosages which have been shown not to cause clinically significant side effects'. The other interpretations are more concerning, of course.
I vaguely remember reading that lithium in low doses has huge benefits with minimal to no side effects, but it's generally not taken due to stigmatization from the downsides of people being forced to take way too much for mental illnesses in the past.
It's not actually especially difficult. People who produce more than their kid needs will sell or give away the extra to people who are struggling to produce enough. Also... Some hardcore body builders buy it as well.
I definitely recommend Baba Is You and FEZ as well. Similarly to FEZ there is a mobile game Monument Valley (and Monument Valley 2) which I adore. It's spendier in $/time, but I find is highly worth it.
Bastion isn't a 2D game, but I'd like to recommend it while I'm at it, it's play is perhaps close enough, and it's stunning.
I agree with Car in that you should talk to them, regardless of how hard it is before modifying anything.
Depending on design, pliers could bend all the points to face downwards.
Ironically the hazardous (to people) goods may well be better for the ocean than most of the rest. Ethanol should disperse well enough and not cause much issue. Fireworks are mostly cardboard. Still a horror show though.
