Deletion of List of scientists active before age 20

Comment: I have taken the other list to AfD, too. This is pure |original research: look up when an article was pubished, look up someones birth date, and calculate a completely arbitrary age cutoff. The same applies here. Are there any |reliable sources discussing "people active as scientists before age xx"? Why 20? Why 21? Why not 20 years and 3 months? Arbitrary OR => delete

Comment: notability not demonstrated in |reliable secondary sources.  Nearly every citation in the article is to a ''Primary Source'' and therefore depends on substantial |original research and |synthesis to support the assertions made in the article
