1 The primary cause of COPD is tobacco smoke (through tobacco use or second-hand smoke).  The disease now affects men and women almost equally, due in part to increased tobacco use among women in high-income countries.
Swarming is the process by which a new honey bee colony is formed when the queen bee leaves the colony with a large group of worker bees. In the prime swarm, about 60% of the worker bees leave the original hive location with the old queen. This swarm can contain thousands to tens of thousands of bees.
A honey bee stings to protect itself or the hive from a perceived threat. The hive contains the queen bee, the young bees and the stores of honey. Bees are programmed to protect their hive at all costs. A worker honey bee typically only stings if threatened, or if you are near its hive. An exception to this rule is the Africanized worker bee, which is known to be more aggressive. Africanized bees may sting with less provocation than it would take for a regular honey bee to sting.
