Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

Proper nutrition is incredibly important for a healthy immune system, normal healing, the list goes on and on... Unfortunately, the exact effectiveness (i.e. an actual number) of proper nutrition at preventing getting sick from the flu is incredibly hard to define or measure.

Where does the WHO get the original virus strain? Do they come from samples taken from humans that have already been infected? I've always been curious about that and this video has not explained it.

250 million world wide? The US population alone surpasses that number.

2019 was nearly the effectiveness try below 50% and lower! For 50% or less my work is forcing me.... literally forcing me with the threat of my employment if I don't get a flu what ever happened to, "My body my choice?"

Isn't proper nutrition MUCH more effective than shots? It works better for me.
