Empirical Determination of the Geriatric State for Individual Health Markers

Marker	Day	Mean	Max	% Max
Speed (µm/s)	12	75.2	207.3	36.3
Max speed (µm/s)	12	188.7	390.2	48.3
Max amplitude (µm)	19	150.6	206.9	72.8
Thermotolerance (hours)	13	2.3	5.3	43.6

Note: % Max = the percentage of the maximal value when geriatric; Day = day of adulthood geriatric onset for wild-type N2 worms; Max = maximum value each marker observed in wild-type over life span; Max Amp = maximum bending amplitude (µm); Max Speed = maximum movement speed (µm/s); Mean = mean value for each marker when N2 becomes geriatric; Speed = mean movement speed (µm/s).
