IF Connie Chung, b.1946 is taking HA, it doesn't really show at her 80 but aging occurs in sudden...jumps or discrete moves, as I witnessed with Dorothy... and consistent with latest aging research. Dorothy looked good at 80 as well, IMO, doing concerts in 2015 up to 2019 to age 84 then at 85, her functions dropped with final shows at 84 and final lesson at 85. Hyaluronic Acid HA shows many Japanese functional beyond 100, so there must be more to it than HA.
