Parents are a bit younger (late 60s), but the biggest thing I keep watch for is their mobility and anything that affects it. My relatives that passed away all had one great correlation in their decline -- the loss of mobility, which really caused everything else to spiral out of control.
Body movement affects a lot of how the entire system works, and also gives them a lot more options to the outside world. Make exercise as fun and frictionless as possible. My parents joined an all-ages ping pong club, a gardening club, and a hiking group... so it covers both physical upkeep to an extent + social/mental one.
