Tarantino, being a connoisseur of Fake Blood, used several types of Fake Blood in the film Kill Bill II ranging from good splatter to free-flowing blood. According to one fanzine, in this film, Uma Thurman killed 88 opponents with a sword. So the numbers(above)are in the right ‘blood-soaked’ ballpark.

The Terrifying Math of Running from a Bear … USA Units
May 14, 2019USA UNITS below. METRIC UNITS here.
BEAR STATISTICS
Grizzly Bear
Weight: 550 lb
Height: 8’ 2”
Top Speed: 35 mph = 51 ft/s
Brown Bear
Weight: 1,500 lb
Height: 8’ 2”
Top Speed: 22 mph = 32 ft/s
Comparing these speeds to the fastest man on earth, Usain Bolt:
Usain Bolt:
Top speed: 27 mph = 40 ft/s
Bears are not dangerous:
………………………………………………………………………
In fact, more Americans die each year from choking on their own vomit than are killed by bears.

Nevertheless, bears are very fast. So you can see why Park Rangers offer the following advice:
More information at Mountain Nature.
The reason for waiting until the bear is 15 ft away is to make sure the spray doesn’t disperse in the air. If the Pepper Spray is too spread out it will not stop the bear.

So Usain Bolt could out run a Brown Bear but NOT a Grizzly!
Bears are NOT as dangerous as:
In fact more Americans die choking on their own vomit each year than a re killed by bears.

Maths News: Volcano Survivor 2
May 8, 2018Kilauea erupts in Hawaii MAY 2018.
The amazing maths of volcano eruptions.
Once lava flows are established new RIVERLETS can run on top of the original lava flow at great speed.
The fastest Lava flows recorded were in Hawaii in 1950 when Mauna Loa erupted. The lava traveled at 6 miles (10 kilometers) per hour through thick forest. But once the lava flows became established and good channels developed, the lava in the channels was flowing at up to 60 miles/hour (97 kph)
Can you out run a lava flow?
You are 2 km from the volcano rim and start running.
VL = 97 kph = 1.6 km per minute (k/min)
= 60 mph
VH = 18 kph = 0.3 km/min
= 11.2 mph (miles per hr )
