I'll say elephant

Guessing elephant

taking a chance on giraffe, sure my theory is all wrong. They are so tall holding head up , may take more blood pumping. As you can tell, no medical background here.

I would say giraffe because of their long necks also.

Also I apologize for my awful answer yesterday. haha

I'll take horse since nobody has guessed that yet, but I think the right answer is giraffe.

My first instinct was giraffe also, because of the long neck.

My guess is elephant, due to their size it would take more pressure for the blood to reach the farthest parts.

Currently it would be all the people under isolation, concerns about income, lost investment value, availability of food and other consumer items and such is a recipe for high blood pressure.

Horse. I’ve seen high strung horses.

elephants to me are the most patient for humans to be around.

I'll say giraffe. They have a low chance of surviving an attack from a predator. (just my reasoning)

giraffe because of the neck

My guess is giraffe, because of the pressure it would take to get the blood up that long neck.
