How do you keep Phileas Fogg Healthy?

One of the things you have to contend with being Phileas Foggs loyal valet is to ensure your master remains healthy. This can be tricky as although you can always attend to Phileas Fogg which will act as a heal, increasing his hit points it comes with the cost of conversing with fellow passengers to unlock more routes. There are multiple events during the game that can boost Phileas Fogg's health such as bribing or sneaking people onboard. This is very difficult and not necessary and you and your master can survive without any help from other people.
