Yes, you can survive without food, but not for too long. Somewhere, I heard the rule of thumb of how long you can go without, is about 3 minutes without air, 3 days without water, and 3 weeks without food.

People can do without sex, as moral people say abstinence until marriage. As with food, I don't expect people to go "forever" without sex. I'm no party pooper. Get married and push the babies on out. Get married younger, if needed. I agree with the "need for sexual relief," but obviously, society expects us to at least wait until we get home, where we might have a little privacy, and not have sex right out in public when we may claim to feel the "need." I take a reasonably liberal view on that, extending "home" to be the tent a family is camping in, an RV, a motel room, an open beach if you are reasonable sure to be alone, a refugee camp, most anywhere a person may reasonably sleep on a bed. As I have said, I welcome people to enjoy "sexual relief," with "unlimited" natural emissions of semen into vaginas, "unchecked" worldwide population growth, natural proliferation of all the more human penises and vaginas naturally coming into puberty and "in heat," just so long as a few basic moral standards are met. The ones I see required in the Bible, and presumably also, by common sense. Commit first in marriage, and love and provide for any babies that happen to happen. That has long been the standard, and I see no reason to change it now. Parents taking proper care of their children, does quite much actually, in order to allow communities to adapt, to hold more people. While the parents take care of children growing up, future needs for housing expansion, can reasonably easily be estimated. And builders can figure where they can make the money in new housing sales. The future occupants are already here, and can be easily counted.

I detest with the way that the natural function of bearing babies, has been relegated into some sort of "voluntary" hobby. No, it's a natural function, much like eating or sleeping. Or the heart beating. And to welcome babies to naturally push out, I see much the same as allowing people's hearts to go on beating. Life is life, and we should be grateful to God, to be alive, that God gave us life.

Also, I think it may have been this same speaker, speaking out on behalf of abstinence until marriage, who suggested orange juice as a contraceptive, if I am stating it right. Now how does orange juice prevent pregnancy? Glad you asked. You drink it, instead of having sex.

For most all of history, sex=babies. Now comes along some bizarre new contraceptive potions and poisons, and sex is not equal to babies? People tend to cling to tradition and moral and religious beliefs, and so we say, "Hold on, I smell a rat." Something's not quite right here. Sex is still primarily for procreation, isn't it? And if not, why not? And the immoral contraceptive pushers have yet to give us any satisfactory answers, how we have the gall to change the parameters that God has set for us.
