So I've looked through the literature and I found a review article saying all of this and more. It was written by a group of respected physicians from American and French hospitals and it clearly supported the widely held belief that you should drink two to three litres of water a day.
This is a common occurrence to have your brood chamber become honey bound during the main nectar flow. A typical hive body will have a brood cluster in the middle and the outside frames will contain honey. A honey bound hive happens when brood begins to emerge, it is replaced with nectar.
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.
