Is blood really blue until air hits it because your vains are blue??

Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. ... But this is wrong; human blood is never blue. The bluish color of veins is only an optical illusion. Blue light does not penetrate as far into tissue as red light.

Explanation:

don't compare yourself to others, this is a big one because due to photoshop and surgery people have this unrealistic image of what they should look like in their head.

think about good qualities you have and jot them down so can go back when you're feeling down about yourself.

make sure you have good hygiene, bathing often, face routine, brushing teeth.

if you'd like to change something set a realistic goal! (;

good question my friend
