It does. A man looks around in sheer panic, sees his mate standing there, they grin at each other and both are immediately calmed.
Although heroism can be part of the experience , heroism is something totally different from the act of enduring of intense physical travail. The person enduring is not being brave. He/she is enduring. A different thing entirely.
A better example than suffragettes (who though brave physically endured little) would be the endurance of the female Jews within the death camps, or the mothers of abolished clans in Tibet or the US POW in North Vietnam some of whom like McCain endured for seemingly endless year upon year.
An anti-example is the POW in North Korea whose group identity was deliberately broken by his jailers. This process is often referred to as "brain washing". Many of these poor individuals, and that is what they were, individuals, simply laid down in their despondency and died.
