1) Neurogenesis halts in your early 20s. After that, no new neurons for you, sorry. Although the connections may change.
2) "Point of view is worth 80 IQ points" is actually one of Alan Kay's famous quips.

This statement as written is almost total nonsense. A cursory internet search yields abundant studies on adult neurogenesis. Even small amounts of cardiovascular exercise increase brain volume, stimulate neural growth, and create synaptic connections in adults well into old age.
At best, one could claim that neuron growth slows as we age, but it absolutely doesn't halt.
The studies which came before may be based on nonprimate animal models in which adult neurogenesis does occur. But the best evidence we have to date suggests that adult humans do not grow new neurons.
