Mike McCastle<br />
If there’s one thing<br />
that winds up Mike McCastle,<br />
it’s when people say stuff<br />
like, “You’re insane, dude,”<br />
or, “That shit’s crazy!”<br />
don’t see it that<br />
way,” the 32-year-old<br />
strongman says calmly.<br />
He’s responding to the<br />
question of whether<br />
it was crazy to try to<br />
“Ijust<br />
break the record for the<br />
most pull-ups in 24 hours, even though<br />
it put him in hospital. Or whether it was<br />
crazy that he set out to pull a two-tonne<br />
truck for 35km through Death Valley, or<br />
to repeatedly climb a 7m rope until he’d<br />
ascended the height of Mount Everest.<br />
He definitely didn’t think it was crazy<br />
when a skinny-ass stranger named Colin<br />
O’Brady asked for training to trek solo<br />
across Antarctica, dragging a sled stocked<br />
with more than twice his weight in food<br />
and gear. Never mind that this task took<br />
the life of British explorer Henry Worsley<br />
in 2016 and was long thought impossible.<br />
From the get-go, McCastle knew each<br />
of these endeavours would bring extreme<br />
suffering. <strong>The</strong>y’re part of a mission the<br />
1.9m tall, 102kg Las Vegas resident calls<br />
the Twelve Labors Project – a homage to<br />
the 12 Labours of Hercules, the ultimate<br />
hero of Greco-Roman mythology. <strong>The</strong><br />
question is: why in the world would<br />
anyone put themselves through all this?<br />
“I’d heard stories about people doing<br />
great things when another person’s life is<br />
on the line,” McCastle says. “I wanted to<br />
test how much I’d be willing to suffer<br />
doing things for others.”<br />
Sacrifice is ingrained in US military<br />
service, and McCastle went into the<br />
Navy after high school, spending the<br />
next 11 years as an air traffic controller.<br />
He also served as a mental and physical<br />
conditioning trainer in a programme<br />
created by the Navy SEALs after 9/11 to<br />
help address a vexing problem: as many<br />
as 80 per cent of trainees drop out before<br />
earning their SEAL Trident. <strong>The</strong> physical<br />
training is notoriously tough, but these<br />
recruits are the fittest of the fit and they<br />
really want to become SEALs, so why<br />
were so many dropping out?<br />
<strong>The</strong> reason is biological. In moments<br />
of fear and stress, the area of the brain<br />
called the amygdala takes over. Part of the<br />
function of the amygdala – dubbed the<br />
‘lizard brain’ due to its primitive nature – is<br />
to identify threatening situations and get<br />
you out. Physiologically, your body reacts<br />
similarly whether you’re facing down a<br />
tiger or engaging in high-intensity training:<br />
your heart rate spikes, you get tunnel<br />
vision and hearing loss; your conscious<br />
brain, laser-focused on becoming a Navy<br />
SEAL, shuts down. <strong>The</strong> lizard brain<br />
doesn’t care about goals, it’s a survival<br />
response. “It happens in a fraction of<br />
a second and gives you no room for<br />
conscious thought,” McCastle says.<br />
