Just stumbled into this thread to see how it was possible that a Kumarbotâ„¢ thread could still - yet again - manage to get >10 responses. Looks like Kumar has to bump his own thread a few times with some confusing, pseudo-provocative language to now get people to take the bait. Guess that's a bit of progress, in some small way. 
It's because animal insulin has the potential for becoming antigenic (mainly from the collection process). Synthetic insulin does not. But, when you're in a poor country, you use what you got.
So, Kumar... hope you give it up man. Most people have caught on that you're just trolling. And, you are an awesomely tenacious troll, I'll give you that. Still, I don't think I'm the only one here who's realized that there's little point in attempting to rationalize with you, especially since you fervently continue to demonstrate your recalcitrance to good science and basic logic, while repeatedly and continuously showing that you will ineluctably confuse the smoke for the fire. No point in attempting to disassemble your unique, countervailing view of reality - I accept that you truly perceive the sky to be purple, and I long ago gave up trying to convince you otherwise. Why? Because I've decided that I really don't care what you think. Besides, I've got much bigger fish to fry. And, you, my friend, are definitely nothing more than a very small fry.

You simply don't have a clue. This is getting fun. Lactic acid is produced in anaerobic glucose metabolism. If you have increased lactic acid levels except short-term after exercise, you have serious respiratory problems.
