> Illness doesn’t happen without a cause Put 20 balls in 10 buckets each. Choose pair of buckets randomly and move one ball from one bucket to the other. After some iterations you end up with buckets withe many balls and buckets with few. You might think about buckets with few balls as 'ill'. Did their illness have a cause? Of course. The cause was the were subjected to random process. Just like your body is when it…
False analogy: the body isn't a closed system with outcomes determined primarily by randomness. Every state is a consequence of prior conditions, even if they're too complex to discern (same as weather).
When you have pseudo random generator then everything is consequences of prior conditions yet some buckets will end up 'ill' and some 'healthy' without any singular cause.
Besides, body not being closed system strengthens my point that its state is result of so many factors that pinning something as vague as being healthy on a single cause (especially internal and psychological) is usually not a good idea. Especially if you don't know the mechanism.
