Mrs Gren
MRS GREN is an acronym often used in schools to help students remember all the universal features that define a living organism. Here is a slightly refined version for you to consider:
Movement
Essential: Action and movement go hand in hand. You can’t grow without action; thus movement, is essential.
Respiration
Essential: Don’t breathe and you die
Sensitivity
Essential: To sense is to perceive; perception enables experience; experience creates understanding; understanding leads to growth.
Growth
Essential: When we stop growing, we stagnate. When we stagnate, we spiritually die; the light of our vitality fades.
Reproduction
Optional, but recommended.
Excretion
Essential: Everyone shits!
Nutrition
Essential: Don’t eat and you die.
Are you still classed as a living organism by these standards?
Enjoy, for now.
