Blood Emerges

The movement of fluids, or circulation, evolved around 3.5 billion years ago in single-celled organisms to distribute nutrients and remove waste. Blood, a specialized fluid carrying nutrients and waste, evolved much later, around 1.2 billion years ago in multicellular organisms. It evolved to feed internal cells and carry away waste. As oxygen levels rose and multicellular life emerged, blood evolved to transport oxygen and nutrients to cells.

Without knowing if the cat is dead or alive, you can think of it as both dead and alive at the same time, or you can think of it as potential. The cat is potentially dead or alive. If both at the same time, maybe the multiverse exists.

What is Schrödinger’s Cat and why is it important?

3Critical Thinking >

Ownership is a social construct: Inside the simple fence, a few individuals enjoy security and resources, while outside, others beg for sustenance. This stark contrast highlights the early origins of resource disparity and the social constructs surrounding ownership.

Is the idea of ownership a real thing?

Emotional Resilience
TAKE-AWAY: Emotional resilience is about developing the ability to withstand and adapt to life’s challenges, setbacks, and disappointments. According to Stoic thought, our emotional reactions stem primarily from our beliefs, judgments, and thoughts about events, rather than the events themselves. By managing your emotions more effectively, you can minimize the negative impact of adversity.
