For people wondering what are the somewhat exact numbers on how to gain/loose dexterity/all thumbs and organised/disorganised. It is calculated based on the weight of the items you are transferring. The "points" you gain in order to obtain or loose dexterity/all thumbs and organised/disorganised are not the same and increments individually. The amount of points you get per weight moved is affected by weight problems traits and the profession of your character. Having weight problems traits is severely detrimental to the gain of points (up to x5 less points). To loose all thumbs, you need to transfer 75k worth of weight. Gaining dextrous is 200k. Loosing disorganised is 100K. Gaining organised is 300K. If you do not have weight problems and do not have the proper profession, you gain x2 the amount of points toward gaining/loosing dextrous/allthumbs. Nurse and doctor gives you x5, burglar X4, electrician and engineer is x3. For gaining/loosing organised/disorganised points it is x3 without a proper profession. Nurse and doctor gives you x5. Carpenter, chef, electrician, engineer, metalworker and mechanic is x4.
