today i learned – weds 10th apr 2019

bit of a weird one today 😏 you know how your cells regenerate? well, is it true that you end up with a new body after a while?

#tdil that it’s a myth that your entire body is replaced every 7-10 years 🤔

it has often been reported that, as all of our cells are constantly dying and being replaced, our body is completely refreshed every 7-10 years 💪 … meaning that we’re basically super awesome reptile beings that shed all the time.

as fun as that sounds … it turns out that, despite sounding reasonable, it isn’t true 🙃. you see, whilst most of our cells are constantly dying and regenerating at different rates, not all of them are … for example – any neurons in your brain that die, aren’t replaced (which is a worry 😳).

if i’m honest, that’s all i had on that bit … i mainly wanted to get back to the whole ‘different rates of regeneration’ bit because it’s interesting!

all of the many trillion cells around your body have different life spans. your red blood cells have a lifespan of about four months and your white blood cells on average over a year! your skin cells live for two or three weeks and your brain cells (usually) your entire lifetime!

with this in mind … here’s something pretty damn cool – whilst your entire body hasn’t regenerated after 7-10 years, various organs have! this means that you have a new heart every 20 years and new lungs every year or so 😱

this was a pretty quick one … but i really like it 😬 it’s mad to think that your organs/skin/etc are often ‘replaced’ 💪 #literallymental

much love 😍 #tdil
