Carbon-based complex life certainly. ;)
Fact is we're used to what we're used to. We've never seen any other
life, carbon-based or not. BTW, this conversation just reminds me of
the XKCD strip of today someone posted here.

Reality is quite different inside neutron stars. There is the
possibility of giant earth-like worlds made of hot ice. If
self-replicating organisms would evolve in some of these environments,
how'd they turn out to be made of?
not really suggesting life would be possible inside stars, just
enumerating the weird places this universe has got...

But they could send their last child to a world with a yellow sun! ;)
