Are sims left handed or right handed?

My main sim is a lefty like me, while his partner is right-handed like most sims. I first noticed him using his left hand when he had a drink and later picked up a serving of food, but I believe left-handed sims also use their left hand when cooking and possibly painting? He seems to hold sparklers in his left hand too. It's a nice touch, although it is a pity we can't just choose it in CAS.

There's also a cheat if you want to make your sim left-handed:

|traits.remove_trait trait_handedness_right

then

|traits.equip_trait trait_handedness_left

I hope you feel better soon. :)
