Sex drive is your vital energy. Many people feel embarrassed to talk about it, but the truth is that a diminished sex drive genuinely signals aging. Don’t think sex drive is something shameful or beneath discussion—it’s the most fundamental expression of human vitality. Have you noticed how sometimes you feel utterly unmotivated—lacking drive at work, passion in life, or energy for anything at all? That’s because all human desire stems from vital energy, and sex drive is its most direct manifestation. A person who still feels sexual desire and impulse is also the one likely to possess that tenacious, never-say-die drive to earn money, build a career, and climb upward. Once that desire fades, indifference sets in—life becomes bland and monotonous, almost monastic; money and career no longer spark interest, and life seems predictable and stagnant. Sex drive isn’t something dirty—it’s an instinct, the innate fuel of life itself. People with strong sex drive typically have abundant energy, sharper focus, decisive action, boldness, and a spark in their eyes. Conversely, those lacking sex drive often drift aimlessly, merely getting by, indifferent to everything, living a dull, lifeless existence. In short: sex drive is your vital energy. Strong sex drive means you’re still young and vibrant; when it wanes, not only does your body age, but your spirit—the will to strive and dare—ages too. Consider older people: even surrounded by attractive men and women, they feel nothing, because they are truly exhausted and aged. That said, while desire is valuable, it must be tempered with self-restraint—excess in anything is harmful, and maintaining appropriate boundaries is the key to lasting well-being.
