While true happiness may have a different definition to each of us, science can give us a glimpse at the underlying biological factors behind happiness. From the food we eat to room temperature, there are thousands of factors that play a role in how our brains work and the moods that we are in. Understanding these factors can be helpful in achieving lasting happiness.

A Guide to the Energy of the Earth
Energy moves in and out of Earth’s physical systems, and during any energy transfer between them, some energy is lost to the surroundings as heat, light, sound, vibration, or movement.
Our planet’s energy comes from internal and external sources. Geothermal energy from radioactive isotopes and rotational energy from the spinning of the Earth are internal sources of energy, while the Sun is the major external source, driving certain systems, like our weather and our climate.
Sunlight warms the surface and atmosphere in varying amounts, and this causes convection, producing winds and influencing ocean currents. Infrared radiation, radiating out from the warmed surface of the Earth, gets trapped by greenhouse gases and further affects the energy flow.

Pet your turtles, they enjoy snugglies more than painI feel like this is especially appropriate for cars and turtles in the road.
And don’t drill holes in them or paint em. Its painful and toxic and you’ll make the poor things cry!
Our turtles love having their heads and chins scratched. And a light pat on their shells. No hits, or thumps. They love good pets, please pet them with love.
Shells are LITERALLY their backbone, imagine if someone thumped you hard on the spine. It would suck right? Don’t do it.
Also their shells are covered in a VERY thin layer of fingernail-like material called scutes. When you paint it, a) it’s very easy for the toxins in the paint to absorb into the turtle’s system and poison them, b) it cuts off circulation to the thin layer of living skin below the scutes, c) it deforms the shell because turtles, especially young turtles, grow rapidly and the paint will inhibit proper shell growth and d) prevents the turtle from absorbing necessary vitamin D from UV rays (you know, that stuff they need to live). NEVER EVER PAINT A TURTLE EVER.
