For me I prevent the getting sick by Washing me hands for like 40 seconds , Try not to get too close to sick people and try to get all of my shots . What do you do to prevent getting sick ?

supercool22 : I give my immune system lots of work, so it stays ready to go... lol. You know, just hang out with the sickest people I know...
But, joking aside, I just avoid sick people, and wash my hands kinda often around sickies. Kinda off topic, but Orange Juice stops headaches... XD

Basically, I rely on my immune system. I don't go all 'ahh, there's a sick person, run!', but I don't get close to them or anything.

I get a lot of rest and I sleep well at night.  I eat healthy foods.  I exercise regularly and I try to reduce stress as much as possible.

I DO hang out with sick people a lot.  The more your immune system gets worked the less sick you get.  Garbage men have been statistically proven to be healthier than most because they're always around trash and they get a workout with their health.  My wife works in a hospital around sick people all day and she's never sick.  She's a trooper.

supercool22 : Well It’s good to do all of what you said but even if you do everything sometimes you’ll get sick no matter what. What I try to do if I feel myself getting a bug I try to nip it in the bud as best as I can. Sometimes, like I said no matter what you’ll do you’ll get a bug every now and then but by trying to nip it, it will hopefully minimize the effects.

I have had full blown flu's a couple of times it’s not fun. I haven’t really been sick in about eight years. The last time I was sick I was going through problems related to blood pressure. I still deal with some effects of it but beyond allergies and an occasional head cold I haven’t been sick.

One thing you can do is research on natural remedies on certain sicknesses. It might help. Researching is a curious person’s best friend. Knowledge is power my friend.

I do allot of things that have been stated by many already.
Exercise, Hydrate regularly, Wash-up like an "O.C.D." Nut, Take a one-a-day multivitamin (Allergic reactions to too much "vitamin-C" force me to take the Multivitamin route. Otherwise I recommend a few glasses of "O.J." a day.), include a good amount of produce in my diet daily.

Though I have developed an odd habit recently.

I try to use a paper towel to use on the exit doors of bathrooms.

I started doing this in my Teens Loosely and Later developed it into a full ritual.
Other than that if it's going to happen? It's going to happen.

There's Other things that come to mind like Brushing in the morning and evening.
Hitting the Shower often.
(Trick for the youth.: Shave after the shower to help avoid unneeded cuts and blemishes. Plus go with the grain.)
Tending to scrapes, cuts, (and smoky nutz) as quickly as you can.
Ummmm.......
Other than that?
I guess the once a year check up is the last thing that comes to mind.
That's it. I'm done. Stick a fork in me.
Good Luck To All.
Peace.

Though I can't manage to stop, not touching your face is a good way to keep away from illness. (and acne, in most cases)

Also, hand sanitizer, hand washing, and staying away from sick people generally works.

supercool22 : actually I hear that getting shot will hurt you wore then it will help you. . . 
 
As for me, I NEVER eat junk food, if I have to it's about four times a year if I had to guess. . .  
 
And I drink FRESH fruit juice straight from the juicer. it's that good. . .

I just wash my hands and that seemed to work. But than again I did get sick over the weekend.  

Absolutely nothing. zero. Nothing I do is motivated by my ability to avoid sickness(other than obvious things like not eating food that's rotten, although I still eat expired stuff if I judge it be ok, and being hygienic, but thats more to not be disgusting).
The amount of times people have been like, dont eat that, its past its expiry date, or dont touch that etc etc. And yet in the last 6 years iv probably been ill about twice, seriously.
I like to keep my immune system on its toes.
Lord iron gut hath spoken.

I don't really do anything spectial to prevent illness, but I rarely get sick. It's partly due to a naturally good immune system, but I also think it has to do with the fact that I don't do overly much to prevent it. Your immune system needs exercise too. If you completely sterilize everything around you, your immune system will start to slack off. However, if you actually use it, it will strengthen and have an easier time fighting off sickness. You just need to think about it and not go overboard. You know, no bathing in toxic waste or drinking out of your garbage can.

I usually stay away from people who has a flu and mostly stay from the outside. Whenever it cold I stay at home and pretty much play other video game. Sometime It best to not get contact with a person who is sick and contagious.
