Alcohol and vitality: the cost most men under-count

Most men estimate their weekly intake at half what they actually drink. The dose-response curve: 0–4 drinks per week minimal hormonal impact; 5–10 measurable but modest; 10–20 substantial; 20+ major.

The realistic adjustments

Three alcohol-free weeknights per week. Move drinks earlier, three or more hours before bed. Track honestly for two weeks. Substitute non-alcoholic alternatives for some occasions.
