Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

The caffeine thing is totally wrong. A healthy adult can safely consume up to 400mg of caffeine a day.

I think the per kg is important there. 192mg/kg of body weight is the lethal dose. So for example a 100kg person would need 19,200mg of caffeine to be a lethal dose. To edit: that's not to say that the lethal dose in this picture is wholly accurate. Caffeine has been known to cause cardiac arrest even in lower doses.

Good point, I hadn’t considered it was based on body weight, and rather thought it was just median population

LD50 is specifically a dose that kills 50% of the subjects.

Lower doses can kill, just less than 50% of people.
