Hollywood star Chris Hemsworth is said to be slowing down, but not considering early retirement, after learning that he's at a "high risk" of Alzheimer's as he ages.

The 'Thor' actor, 39, discovered that he could be vulnerable in later life to the degenerative disease while he filmed his National Geographic and Disney+ docuseries 'Limitless', and sources say that even though he is planning to keep an eye on his Hollywood workload, he is not considering early retirement for the sake of his health, reports femalefirst.co.uk.
