Ottoson Partners Real Estate Robe and Robe and Community Bendigo Bank are raising funds as part of the Big Freeze 3 to Fight Motor Neurone Disease (MND).
Staff are participating by wearing their beanies and donating money to the Big Freeze 3.
The Big Freeze has so far raised $319,182 towards finding a cure for MND.
Motor neurons are nerve cells (neurones) that control the muscles that enable us to move, speak, breathe and swallow.
MND is the name given to a group of diseases in which these neurones fail to work normally.
Muscles then gradually weaken and waste, as neurones degenerate and die.
Motor function is controlled by the upper motor neurones in the brain that descend to the spinal cord; these neurones activate lower motor neurones.
The lower motor neurones exit the spinal cord and directly activate muscles.
With no nerves to activate them, muscles gradually weaken and waste.
MND can affect a person's ability to walk, speak, swallow and breathe.
Your help is needed to fight MND.
This means freezing some of the most famous Australian sporting personalities in ice-cold water in front of a blockbuster football crowd at the MCG last Monday.
All money raised goes towards vital MND research into finding potential treatments and a cure for Australian MND patients.
