With regards to Lifestyles, one of my favourite ways to go is:
Mild Allergy to Soy,
Make sure that I have High Necessities to cover that all my food is "Real Food", not Soy,
So, I tend to do:
Comforts, Entertainment, Security at Middle(3), Neighborhood at Low(2), Necessities at High(4)
It ends up giving you relatively free points. Since, after all, a mild allergy is only a -1 to your Dice Pools,
so, in general, even if you end up having to eat soy at a meet, it is more a discomfort allergy, not a dangerous one(I have
a few of these RL, namely to onions and black olives). And, of course, it meets one thing any GM would like:
it is a disadvantage that actually impacts the game, and will come into play...
