I can’t stand it when people stop themselves from making a decision by constantly asking “what if”. Just check the important factors and do it! But this doesn’t apply to health.
Eating an extra kiwi could extend my life by an hour. Blinking a few more times while reading could keep my eyesight from worsening.
It’s impossible to know which minuscule decisions could lead to drastic effects, and this is sombre. The only way to make them a non-issue is to fully control our health. We are still far from making this a reality.
