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.
Pick the right time to harvest. On a sunny day, most bees are out foraging between the hours of 9:00 AM and 4:00 PM. Harvest the honey within this time frame so that there are naturally fewer bees to deal with.
