Life, a definition?
How would you define life?
Here is a definition. Life is about:
Growing
- From birth to death, an organism grows. Plants, fungi, humans... except
for viruses, but are they living organisms?
Moving
- Movement is the first thing that would tell you if one is alive or
not... although plants themselves do not move, there is movement inside.
Eating
- Exchanging matter with the outer world is a sign of life: it starts
with breathing, then ingesting matter (and its excretion), metabolising,
and even talking and hearing (feeding those grey cells!)
Breeding
Life has this unavoidable property to multiply itself. Anything will
do the trick. It seems we are just here to pass life around.
