Perhaps the thing that makes humans truly unique on Earth is that we are never satisfied with our situation; maybe that is what's taken us so far.

Humans may be the only creatures on Earth who spend significant time thinking about the fact that someday their lives will end.

We are all born with a unique genetic blueprint, which lays out the basic characteristics of our personality as well as our physical health and appearance... And yet, we all know that life experiences do change us.

Humans are upsetting a fragile balance that their own human ancestors established.

There's no such thing as a free lunch, at least on the karmic level.

We humans have millions of years of evolutionary baggage that makes us regard competition in a deadly light.
