Hi Scotti,

Going to Pennsic?

Unfortunately the connection between the cleanliness of water and health 
was not a very well established item until well after the 16th century. 
Witness the placement of outhouses and water sources next to each other and 
then folks wondered why certain communicable diseases florished.

FWIW, 6000 Kcalories per day is about 6 horse power-hours. Not a totally 
unreasonable work output for a 12 hour day (yes by modern day measurements 
it may be extreme). Even at 4000 Kcalories the calories in small beer are 
significant. IN a 10 hour day, a 160 lb person will expend 3840 calories 
digging in a garden or carrying wood, 4600 chopping wood, 3450 doing 
general gardening, 6150 general forestry, 5380 masonry, etc.
