Whats wrong with Gak ?

[Shane]

Gak has a tiny health bar for some reason, no matter how much i eat, rest and drink...
His health circle wont expand anymore to full size...

I have used him a lot and he has been through tons of battles so im guessing that perhaps some injury or something, but maybe one of you can explain further why a health bar reduces like this... etc

also can it ever be repaired in some manner...

Technically that's your "Life Expectancy Meter" - so the size of the circle represents the primate's overall well-being.

It will shrink naturally over time as your primate ages. It will shrink faster if your primate takes a lot of damage and/or you don't keep him well fed, hydrated and rested.

And resting isn't just sleeping - make sure you pause from time to time to catch your breath as you're doing strenuous stuff like climbing trees or rocks, jumping around a lot or sprinting a lot.

A red ring appears around the green circle when you do ^this stuff. The longer that ring is there, the faster you're lowering the primate's life expectancy. Do the best you can to keep that red ring from sticking around to extend your life expectancy.

But the bottom line is, all primates will eventually get too old to exert themselves for long periods. At that point consider switching to a primate in better condition or advancing a Generation.

i switched to another ape, and a few hours later his circle has expanded, still not full yet, but he looks better shape
