I know the feeling MnM! You've done very well with your family to have your eldest reach 60 on your first generation.

To really give them the longest life they can get, try to get some fruit and vitamins into them if you can afford it, as well as any health-advancing things like the hand gel. Praising them when they exercise really seems to help as well! I always try to keep their health bar full.

Even with a full health bar they all have their time to pass away and it will be hard to take when it does happen. I hope they don't go too soon but it must be getting close.

Welcome to the forums by the way!
