Depends on who you are and where you live. If you are rich(have food, water, and a place to live) than it's mental. You don't have much need for physical stregnth besides being fit, which is more of a choice. You can afford the loss of sanity, because you care about alot. When you are poor and all you can worry about is your next meal than pribably physical, your mind is too set on survival. There is no room to loose your mind on anything,.
its opinion, an idiot can be happy and humans are the only animals that can survive without a good brain, but you wont live well. Without physical strength you don't have freedom, you have to rely on others for your life, but everyone does that anyway.
Mental. Although you need to be strong physically for things, if your mental health isn't well, the rest isn't going to matter very much.
Probably have to go with mental strength, You'd obviously would have enough mental strength then to gain more physical strength.
mental strength, without it, whatever physical strengh you do have wont be of much use
Mental strength. You cant have physical strength without mental strength.
