That's because emacs thinks "years." is an abbreviation. If you'd use
two spaces after a dot ending a sentence, it'll work as you expected.
You can change this by setting this to nil.
,----[ C-h v sentence-end-double-space RET ]
| sentence-end-double-space is a variable defined in `paragraphs.el'.
| Its value is t
|
| This variable is safe as a file local variable if its value
| satisfies the predicate `booleanp'.
|
| Documentation:
| Non-nil means a single space does not end a sentence.
| This is relevant for filling. See also `sentence-end-without-period'
| and `colon-double-space'.
|
| This value is used by the function `sentence-end' to construct the
| regexp describing the end of a sentence, when the value of the variable
| `sentence-end' is nil. See Info node `(elisp)Standard Regexps'.
|
| You can customize this variable.
`----
However, keep in mind that then the sentence moving commands like `M-a'
and `M-e' also stop at real abbreviations like in "bla, bla, etc. bla
bla."
If you check some messages here on the list, you'll see that most
long-time emacs users have two spaces after the dot ending a sentence.
Ditto in this message. Now you know why.
Bye,
