Sloth bears likely became ant/termite eaters due to the overwhelming abundance of the little insects. One thing all bears have in common; a bear will readily take the easiest meal available. If he were to have acquired his feeding habits from the fear of the tiger, wouldn't it make more sense to choose something up high, in the trees, rather than on ground-level? The fact that the courageous little sloth bear will sometimes stand his ground against a tiger that outweighs him by a hundred pounds or more convinces me that fear had nothing to do with his choice of diet.
You should have read in the article i posted, fast twitching muscle fibres are dependant on slow twitching fibres for nourishment. Perhaps, some difference is there in this ability to nourish fast twitching muscle fibres that make the difference between bear and big cats. This is just my assumption.
Drooling
Drooling is defined as saliva flowing outside of your mouth unintentionally. It’s often a result of weak or underdeveloped muscles around your mouth or having too much saliva. It may also be caused due to inability of animal to control it's muscles. Drooling can be a symptom of a medical condition, developmental delay, or a result of taking certain medications. Anything that leads to excessive saliva production, difficulty swallowing, or problems with muscle control may lead to drooling. Drooling is usually caused by excess saliva in the mouth.

Bears have very careful control of their muscles, and this trait is shared especially among predators. Very fine reflexes and coordination. The video you just posted clearly shows extreme grappling coordination between the two bears. You didn't mention anything about a heart this time either....I wonder why?

Bears have high control on their muscles during normal times. But when pushed to extremes, they seem to slightly lose it. Losing control of your mouth muscles can be due to improper nourishment of muscles during highly demanding tough conditions that is done by heart. I already said when pushed to extremes they gasp severely that may be due to weak heart. While in tigers and lion fighting there is no drooling. They get tired but you see the bears are severely tired and gasping.
Let me put it to you like this Parvez; those are Alaskan peninsula grizzlies which are near the size-range of Kodiak brown bears. They can, if need be, keep up such a fight for hours. But, these guys normally end a fight in just a little while. No lion or tiger would wish to push a fight against a big Alaskan grizzly boar.

You can hear lions gasp after a long bout as well, and I've watched many bear and big cat videos. Again, doubt bears have weaker hearts. Scientific research must be conducted for this.
