Stamina: Is that related to our body weight, height or our perseverance to achieve something ?Every one has good body physique and when it comes to stamina many would fail to maintain. Though they look hefty and strong, they could not lift even small things and seek help of others. On the other hand those who are lean can lift the things easily and also feel light while doing work. What is your opinion about stamina ? Is that something concerned with our body weight , or something concerned with our height, or something concerned with our determination and perseverance to achieve a goal ?
