How to overcome impotence?

Many men ask this question over 35. Erectile dysfunction is now overtaking young men. Stress, ecology, poor-quality nutrition lead to disruptions in the work of the young man's body, resulting in so-called misfires, but what can we say about the older generation. In the modern world, everyone knows about Viagra, both young people, for whom Viagra is a kind of doping for performing all kinds of sex marathons and the older generation for whom, for various reasons, sex becomes impossible. Is Viagra (Sildenafil Citrate) the best drug? There can be no definite answer. For one, it is important that the drug is a brand, and for another, the price / quality ratio is important, what is the difference what the name of the tablet is - the main thing is what is inside it. I suggest you draw your attention to the drug Kamagra, which consists of the same substance as delusional Viagra, namely, Sildenafil. It is a great counterpart to the well-known Indian origin brand for a reasonable price the same active substance, the same action and the same side effects. Nothing new and nothing extra, so why pay more? I propose to answer this question in the comments. Share your opinion or advice and tell your story.
