There is a spider that when chased by a Gecko, it has a heart attack. Then it can't run from the Gecko properly, so it tries to make its escape by rolling. I've heard that's not very effective. So remember, if a gecko ever chases you, an you're so scared you have a heart attack an you can't run, don't try an roll away. Unless I don't like you, in which case, ignore that advice, an roll for your life.
I have a few questions for you: Do you think this spiders heart is especially weak, an that is why it has this trouble ? Do you think It's very fragile an scares easily, but it has a regular spider heart? Or do you think it just can't cope with stressful situations? Do you think possibly it somehow forces itself to have a heart attack as a method of suicide, because it would prefer that to getting crunched by the Gecko? Also, is there anything you find so scary, that you think if you ever encountered it, you'd have a heart attack?
Gecko says: "You're pathetic spider". spider says: "Gaaaah!!! this could turn nasty!! I best be on meeee waaaay!!!!!!!!"
