It is because it uses mental stamina. ;)
Stamina is your ability to withstand physical and mental effort. For example, athletes have very good physical stamina as they are able to compete in sports for very long periods of time. Other people might do very well in long exams as they have good mental stamina. If you have bad stamina, you might find yourself getting tired quickly as the result of straining yourself either physically or mentally.
Stamina is your endurance. For example, the more you run, the longer your stamina will be. It relates to fitness because the more stamina you have, the longer you'll be able to participate in athletic activities.
mental illness has no correlation to sexual orientation. The gay community is affected by mental illness in the same way that the straight community is.
There is no adjectival form of the noun stamina. You would have to recast your sentence. For example:'My friend had enormous stamina when she was running the marathon.''I have noticed that David's stamina has decreased over the past few months.'If you are taking the word stamina to mean high stamina (as opposed to being just a neutral synonym for staying-power, with no indication of how much of it the person in question has), and you want an adjectival equivalent, you could perhaps use powerful or energetic, although they are not exact synonyms.
joe Jonas is gay

It is all mental, you know that you have the band on and that if you have the band on you will have better performance
Watermelon mixed with lime helps stamina. For stamina besides mental grit and systematic practice proper nutrition is beneficial. Watermelon contains water with nature's vitamins and the mild sweetness gives glucose. Lemon is packet full of vitamins. Both are nutritious. They are good at all times. Good for stamina too.
If you are mental, gay and very stupid. :P
No. Fortitude is strength, stamina, so you can have mental, emotional, or physical fortitude. But "excess verbiage" is redundant. Verbiage is an excess of words, especially useless ones.
