If love were an animal, it would be a tardigrade.
http://en.wikipedia.org/wiki/Tardigrade.
They are tiny little water born segmented animals the size of a dot made by the tiniest pencil.
Tardigrades are classified as extremophiles. An extremophile is an organism that can thrive in a physically or geochemically extreme condition that would be detrimental to most life on Earth.For example, tardigrades can withstand temperatures from just above absolute zero to well above the boiling point of water, pressures about 6 times stronger than pressures found in the deepest ocean trenches, ionizing radiation at doses hundreds of times higher than the lethal dose for a person, and the vacuum of outer space. They can go without food or water for more than 10 years, drying out to the point where they are 3% or less water, only to rehydrate, forage, and reproduce.
True love would live in space without a space suit, withstand extreme pressure, extreme temperature, withstand radiation and would be able to go without food or water for more than 10 years without drying out.
