This would be a very time-consuming experiment. Any attempt to combine this with other experiments by ANOVA would probably push the end-date out by months, and one would start to be seriously concerned that changes caused by aging or environmental factors would contaminate the results. A 5-year experiment with 7-month intervals will probably eat up 5+ hours to prepare <12,000 pills (active & placebo); each switch and test of mental functioning will probably eat up another hour for 32 hours. (And what test maintains validity with no practice effects over 5 years? Dual n-back would be unusable because of improvements to WM over that period.) Add in an hour for analysis & writeup, that suggests >38 hours of work, and 38×7.25=275.538 \times 7.25 = 275.5. 12,000 pills is roughly $12.80 per thousand or$154; 120 potassium iodide pills is ~\$9, so 365.25120×9×5=137\frac{365.25}{120} \times 9 \times 5 = 137. First quarter at 1:20 AM. Second quarter at 4 AM. 20 minute nap at 7:30 AM; took show and last 2 doses at 11 AM. (If I feel bad past 3 PM, I’ll try one of the Modalerts or maybe another quarter of a Waklert - 150mg may just be too little.) Overall, pretty good day.
