I was convinced I could swim a mile as a workout when I was a teenager. I got maybe 25 yards in before giving up. It took me 5 minutes to go that 25 yards because I kept sinking. To this day, I can’t float or tread water and I swim every week with a swim coach. If I stop swimming, I sink a few feet below the surface, and as air leaves my lungs, I go straight to the bottom. So I am in awe of anybody who can swim across the border, especially if they’re going against the current. That shit is HARD.
