    If anyone is interested in human anatomy the best success that I have ever had was by using the Anatomy Blueprint Pro (just google it) without a doubt the most incredible course that I have ever followed.

    In one condition the heart can break up if your boo leaves you or dies lol Tamotaubo is also known as broken heart syndrome Takotsubo cardiomyopathy is a temporary heart condition that is brought on by stress. It has the same symptoms as a heart attack but is not caused by any underlying cardiovascular disease. It is also known as stress cardiomyopathy, apical ballooning, or broken heart syndrome.

    Don’t know if this is true but I read somewhere that your heart strings can actually break off if you experience serious heartbreak so the phrase ‘tugging at your heartstrings’ has some depth 😂

    quick tip for ya'll who have a hard time watching it cuz he's going to fast: change the speed in the video to 0.75 and he's actually talking at the speed of a normal human. Really helped me out
