Tatooine causes people to age in dog years.
I agree somewhat with this, but i also look at force users as people who age faster the closer they are to the force and how they harness it.
Obi-wan aged the way he did because of a mixture of stress, the planets conditions & the force within him causing him to age that way.So you’re saying that without the Force, Yoda would have lived 2,000 years?
Maybe that’s why Grogu is 50 and still acts like a baby, despite Yoda having been training Jedi at 100ish.
