Tintin in CMAJ

The article by Antoine Cyr and associates1 is a fascinating perspective into the enigmatic delayed development of Tintin. The researchers must be commended for such insightful extrapolation from the limited source material. One wonders about Asterix and Obelix and the possible glandular or other systemic deficiencies that might be contributing to their sizes, body masses and apparent halted development. Perhaps the toxicity of cartoon ink should be independently evaluated.
