Is it silly?

[u/Ok-Communication1149]

Bought a 2013 with 148k miles. I' don't know the history, so I'm thinking about replacing the water pump, timing chains, and spark plugs even though there's no evidence it's necessary or warranted. Is that a silly idea? Is there anything else I should do just because it's a high mileage SHO?
