> A 95-year-old former dentist has set a new world record for his age group in the 200-meter indoor sprint, knocking a massive 2.4 seconds off the previous record…
It is in the first line of the article.
I believe the parent is referreing to the fact that the specific age range is not specified. Eg. is this 90-99 (my guess), 70+ or "exactly 95", etc.
A caption on the video says it's the over-95 age group.
