Can an employer decide not to hire you if you are a smoker or you are obese?

Can an employer decide not to hire you if you are a smoker or you are obese?
 i think that it depends on the job occupation because if the job has a rule against smoking than they can decide not to hire you. Because maybe at a doctors office they can't hire you because there is no smoking at a doctors office. It depends..

And if they don't hire you if you are obese then maybe it also depends on the job occupation cause if you are a yoga instructor or an instructor of some sort they don't want someone who is obese to be training others because maybe they want someone the trainees can look up to. But they can't just not hire you because you are obese because maybe you are a very good hardworking person.

Problems i ran into yesterday...

The problems i ran into during yesterdays assignment were finding wether they were hiring because usually the businesses don't post anything up on the internet. They usually just put out signs outside of their business. :p

what can we learn from the city job fair?

what we can learn is to get businesses who actually want to hire because if we get businesses that do not want to hire then what would be the point of them coming to this job fair? we can also advertise correctly. As in make sure to tell the public where its at, when it is, and tell them what the purpose of the job fair is.

seating arrangements

i will benefit from this because I am able to work around other people and get help from a new perspective when i need it. The people around me will benefit from this because when they move they will be able to get help from other people other than the people who they've worked with for the first part of the school year.

3 Positive Characteristics

The 3 positive characteristics that would make me the best employee would be that when they tell me to do something, i won't give up right away i'll give it a few tries and if i can't do it then i'll ask for help.
Another positive thing is that i i can dress according to the dress code. Another thing is that i can be a good person when it comes to working with others.

The 3 negative characteristics would be that i can sometimes have an attitude. When i get angry or upset, its best not to talk to me because i'll just get even worse. Another thing is that I can sometimes do what i want because i always think that i can sometimes not listen cause i get bored of listening to people. And the last one is that i don't like to do more work than what i have to do.
