as a simple example, you and your bf now swap boats

the lw boat your bf is in will be deeper in the water than when you were in it >> more drag

his boat that you're in now sits higher in the water >> less drag

the boats are designed for different weights but thats not really what we're looking at here, we want to know how much water is displaced as that determines the amount of water-boat surface contact surface area and hence the drag.

A scull rated to a heavier weight does this by being wider and/or longer, increasing the water-shell contact area [which is the key thing as by spreading your bfs weight over a larger area the boat 'sinks' less and has the right water clearance] and increasing the drag

SF was 4-3 before acquiring arguably the best offensive player in the NFL, then lost to KC before their 10 straight. Their 3rd string qb might not be the biggest reason they're winning. Replacing Trey Lance and acquiring McCaffrey are most likely the reasons their offense got better and had more impact on winning.

It seems like it is self reported weight rather than their actual weight, that might explain the peaks on triathlon, athletes could be rounding their weight to a nicer number , e.g. reporting 80 instead of 81.5, or 75 instead of 73.9. Do those ‘peaks’ in triathlon actually correspond to round numbers?

As a foreigner, this looks awful to me. More than half the americans think a person should have sex for a first time in his twenties. And more than one in four think sex shouldn't happen out of marriage? It's like noone actually considers how this affects ones self esteem, motivation to socialise, skills e.t.c.
No wonder why there are groups on reddit for pickuplinery and douschebaggery and how life for men before 30 sucks. And only like 30 percent approve pornography? This a seriously sexually repressed culture... I am at the same time disgusted and sad...
