I agree. Last month I went 11 days while only drinking water. No food. And the first 7 days I barely noticed. I had no hunger at all. On the 7th day I went for a 12 kilometer walk. I had plenty of strength.<p>After the 7th day I did start to suffer weakness, and I had a busy schedule at work, which put a limit on how long I could fast. The night of the 10th night I slept for 16 hours. The 11th day (a Saturday) I walked 10 kilometers, but it was much more difficult than walking 12 kilometers 4 days earlier.<p>I doubt I&#x27;ll ever again do 11 days when I&#x27;m working. Maybe on vacation, but not when I have work to do. However, doing 7 days is something I plan to do this month. Because 7 days without food imposed no limits on me, at all.<p>It has health benefits, it imposes no burden, and it&#x27;s easy to do. I don&#x27;t think we need to wait for a drug to be invented, when the solution is so easy and available.
