I phil for Kai's health. I would fear for his health more if he decided to chase Phil - I would then fear for Phil's health too at levels even higher than those that I currently fear for the health of Phil at, as he escalates the supplements upward in order to ensure he beats Kai.
I would fear for both of their healths even more that my normal scared level. Very scared level. I get very scared when I think of the health of Kai and Phil.
Neither of them are my tenants, so I don't are if they live or die. Just make it entertaining for us no matter what.
