It does what it says it will...
I didnt really expect too much (Im in an A&P II course, so were going into some pretty serious depth on some of this stuff) but some of these facts are pretty fun. An average male produces 14 gallons of sperm in his lifetime! Ive always wondered.
Oh, and it does indeed give two different measurements for the total length of the blood vessels in the human body, BUT its kinda close- it says 100,000 miles on one factoid, but it (probably) meant the more accurate length of 100,000 kilometers- or 60,000 miles, as it accurately says in the other fact.
