Average food consumption per person per day: 5.26 lbs
Average water consumption per person per day: 4.18 lbs
Average mass consumption per person per day: 9.44 lbs
Someone will consume 94 pounds over the course of 10 days. Give or take.
Hypothetically, if you had to ship a friend to Italy, it would take 10 days by UPS, and the box would weigh roughly 224 pounds. If they fit inside a 3 foot cube box, which would be a bit cramped but survivable, then the billable weight is 282 pounds. As long as you stay under that, the trip from Austin, TX, USA to Salerno, Italy would cost $553 and take about 8 days.
That’s assuming that the person in question was worth 1 dollar. The EPA values a human life at $5.5 million dollars, but UPS won’t insure that much.
If I value my shippable friend at $1 million, the price rises dramatically to $8996. An airline ticket costs about $1500 from the US to Rome, so the break even point there is when the person in question was worth $120 thousand. Then the air freight cost would equal $1500 or so also.
