I would only be guessing, but I’ll give it a shot. General insurance appears to make greater use of statistics than life or health insurance. Also, the legal structure of products is much more complicated, so a good understanding of the law as it affects the products is probably needed. Finally, general insurance is generally “bought”, while life and health insurance is more frequently “sold”. People are more likely to be proactive in buying general insurance and more reactive in buying life and health insurance. Thus, the two markets have different nature. Sorry I can’t be more specific.
