How strong can you become? Test your own strengths as a point of personal curiosity for yourself.
Testing your strength as a matter of personal pride
There is no real or ‘rational’ purpose behind testing out strength. But it seems testing our strength is all about EXPENDING our strength, and FORCING OUT our strength, rather than mere conservation of our energy and strength.
And perhaps it is also about conserving our strength TOWARDS EXPENDITURES which we care for.
