Thanks. I haven't used liquid products much before. Anything you've noticed that's significantly different in terms of onset time, effect duration, etc?

Anyone know where I can find melatonin tablets <300 mcg? Splitting 300 mcg into 75 mcg quarters still gives me morning sleepiness, thinking smaller dose will reduce remaining melatonin upon wake time. Thanks.

Surely, as rationalists, we should

So awkward it hurts that this is even a thing.

404: Generalized model not found

Any particular evidence in favor of this approach, anecdotal or otherwise?

Seem to be implying that you are more likely to be in a simulation if historixcally impt. Interesting

Wear a Helmet While Driving a Car

No other source, but keep in mind that helmets are tuned for a certain force level. Too durable and helmet does not reduce peak force as it does not crush. Too weak and it crushes quickly, again with little reduction in peak force. This should just empasize to use the 25% number here though since the forces are more representative.

Redacting "won't do much of anything" except as implied by 25%, but keep in mind that if peak accelerations are much higher than the given case, the helmet will be less effective due to the above. This may or may not be the case in car crashes depending on speed.

Interesting - thanks for checking this. If the Severity Index is claiming no significant damage below 1200, I think it may be incorrect or may have a different criterion for severe damage. Some helmet standards seem to be fairly insensitive, only accounting for moderate or severe brain injury whereas MTBI can have long lasting effects. Yes, I discount Severity claims as the metric does not appear to give reasonable results. 188g is a crapload of linear acceleration, but metric puts it under threshold...I dont buy it, so am left to judge on peak linear accel instead (shame that rotational accel was not measured...)
