(HOUSTON CHRONICLE) — Like many preschoolers, Christopher Salvaggio fires off a seemingly incessant stream of questions.

But some of this Houston native’s questions – such as “What happens to food after you eat it?” – are a challenge for his parents to answer in enough detail to satisfy his seemingly endless appetite for knowledge.

The 3-year-old, who now has a working knowledge of the solar system, the cardiac cycle and the work of Pablo Picassio and Vincent van Gogh, was accepted last week into Mensa, a society for those with IQs in the top 2 percent of population.

Christopher has an IQ of 145 and reasoning and thinking abilities that exceed 99.9 percent of children his age, according to his evaluation.
