A child’s eventual height and body composition depend on genetics, nutrition, hormones, health, and many other influences.
A birth weight of 7 kilograms therefore does not prove that the child will become exceptionally tall, unusually muscular, or physically distinctive later in life.
It also cannot establish what a person looks like at age 40.
To answer that question about the specific child mentioned in the headline, reliable identification would be necessary. A recent photograph would need to be linked to the correct person, and the person’s age and identity would need to be supported by credible information.
Without that evidence, any description of his current appearance would be speculation.

Some children enjoy hearing that their birth was memorable. They may laugh at old photographs or ask relatives to repeat the story of the day they were born.
