On 28 March 1941, Virginia Woolf filled her pockets with stones
and walked into the River Ouse,
which together with its main tributary,
the River Uck,
drain over 250 square miles of Sussex
via streams,
rivers
and various other dendritic tributaries.

While the water temperatures were surely harsh,
historical weather patterns suggest
relatively calm surface tension,
and relaxed yet steady currents,
allowing for swift submersion

Taking into account,
the chilled morning winds,
her quickened, shivering breaths
likely led to hyperventilation.

In turn delaying the breath-hold
break point, and allowing blackout to occur
without warning
due to hypocapnia.
While unconscious, water can more easily enter the lungs
to induce a wet drowning,
as it is no longer inhibited by laryngospasm
or coughing.

The Missouri River,
by contrast,
rises in western Montana,
flows east and south for 2,341 miles
before entering the Mississippi River north of St. Louis, Missouri
taking drainage from parts of ten U.S. states
and two Canadian provinces
to form the fourth largest river
system on Earth.

At some locations throughout its course
the current surges so fiercely
that old-growth trees are felled,
steam ships are consumed beneath white caps,
and swaths have continued to go undeveloped well into the 21st century.

When lowered into water cooler than about 70 °F,
the diving reflex is triggered and protects the body
by putting it into energy saving mode
to maximize the possible time spent under water.

This reflex action is automatic
occurs in all humans,
and is likely a result of brain cooling similar
to the protective effects
of deep hypothermia.

Of those who die after submersion in freezing waters,
around 20% die within 2 minutes from cold shock.
Uncontrolled rapid breathing and gasping causing
water inhalation, panic,
massive increase in blood pressure and cardiac
strain leading to cardiac arrest.

As this occurs while submerged
rather than the hyperventilation seen in panic attacks,
crying, or shivering on land
any additional survivability that may be gained,
becomes almost immediately fatal.

In order to combat the effects of
instinctual survival mechanisms
once bare skin breaks iced surfaces
such as panicked clawing back to shore,
rescue attempts from passersby,
and even simple reconsideration,
cold water drownings,
despite representing only 2 percent of suicides,
reveal a visible trend regarding near mandatory use
of bricks,
stones,
or other weights,
in order to overcome
buoyancy,
the names of pets,
canceled brunch dates,
birthdays,
and the forced finality
of questions left unanswered
or perhaps answered too clearly.
