55 is quite low. Although it depends on height. I'm 16 years old, not bearded, 182 cm tall, and weigh 62-64 kg. Am I normal?
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
