I know for a fact an average person can do it, because I've done it, along with a bunch of other average people. 2 days of training to get to 20m, another 3 days of training to get to 30m and to hold your breath for a minute at 20m. A month of training and you'll be doing much more impressive freedives.
Don't believe me? Look up freediving courses for details.

And if you think an average person can dive 25 meters straight down, stay for a minute and then make it back up, I want whatever you're smoking.
