A quick google shows people estimating 500-750 kcal/hour when swimming the English Channel. And another big range, but it looks like ~15 hours is a decent estimate for a one-way crossing, so that’s ~7,000-11,000 kcal, which assuming 3500kcal/lb of fat, that’s 2-3 lbs.

This is all ignoring the fact that most of the energy burned is actually glycogen and food consumed during the swim, not fat reserves.

Not to undermine your point about forklifts being more dangerous than cars (no idea personally, I don’t have any firsthand experience, only horror stories I’ve read on the internet), but I wonder if accidents/injuries per vehicle per year is the best measurement of danger considering I would assume most cars are only driven for about an hour per day, but I would assume forklifts are operated for about 8-12 hours per day.

It looks like they were, there’s an arrow on the right side of the image as well. It must have been a screenshot from a photo album or the webcomic website.
