Ancient Chinese nobility committed suicide by eating a pound of salt.

You’ve all heard that too much salt – just like everything else that is not done in moderation – is harmful for your health. And you don’t need to be told that too much of it can be fatal. In actual sense, a person only need take a single gram of salt per kilogram of weight to lay themselves on their deathbed.

And in ancient China, this was a method employed by nobility to commit ritual suicide: a pound of salt would be enough to send them to meet their maker – for only they could afford such copious amounts of salt given its high price tag.
You need to find a balance since apparently, too little salt is also deadly for you. Your body needs salt and if you drink lots of water, what you are doing is flushing the salt from your system, thereby leading to fatal Hyponatremia. A woman going by the name Jennifer Strange did something, well, strange: she died for this same reason after she decided to enter into a rather strangely-named competition called ‘Hold your wee for a wii’.
