I wouldn’t make too much of this. Ginsburg has one foot in the grave and the other on a banana peel. She probably is doing well just to get up in the morning.
When they gave justices lifetime tenure, our Founders never dreamed people would be living and thus, serving, into their 80s and 90s. This needs to be changed to a term of 20 years, max.
Then they were very unobservant, as Benjamin Franklin was 81 when the Constiution was adopted.
