VALENTINE’S SCIENCE EXPERIMENT
👨🏼‍🔬 ❤️👩🏻‍🔬
1) Stick a straw into a blob of Blu-Tack or plasticine
2) Lay on your back and find your pulse 
3) Rest the Blu-Tack on that spot so you can see the other end of the straw
4) Marvel at your own heartbeat
BUSY HEARTS:
❤️Your heart beats 70 times per minute at rest. Less if you’re really fit, more if you’re not so fit. That’s 100,800 beats per day!
❤️ Your heart has the fastest metabolic rate of all your organs, on a pound-for-pound basis. The metabolic rates per kilogram of tissue per day of your major organs are as follows: 
HEART: 1830 kJ/kg/day
KIDNEYS: 1830 kJ/kg/day
BRAIN: 1000 kJ/kg/day
LIVER: 830 kJ/kg/day
SKELETAL MUSCLE (at rest): 55  kJ/kg/day
FAT TISSUE: 20  kJ/kg/day
❤️Your heart weighs about 300 grams, whereas your brain weighs about 1.3 kilograms. Therefore, your brain consumes more energy in total but…
❤️If all your organs and flesh burned fuel at the same rate as your heart, you would need to eat FIFTEEN times more food per day than you actually do. Instead of 8700 kJ per day, you’d need to consume 130,000 kJ per day (in the old money, that’s 30,000 Calories instead of instead of 2000 Calories)
