|No, not those shots.|
"To subdue the enemy without fighting is the acme of skill." -Sun Tzu
The thing about healthcare is you'd rather not need it.
Doctors, Nurses, EMTs and Pharmacists have raised the level of medical care far beyond what was available one hundred years ago. They can win battles that you are better off not fighting.
Like the seatbelt in the car, if you need it, something else has gone particularly badly.
Inasmuch as you have an option, pound of cure is the default. The 'ignorance is bliss' approach just fixes things when they break. Doctors. Casts. Drugs. All to put things back the way they were before.
1: Keep your hands clean. Wash off the bacteria regularly with soap and water.
2: Floss. This is your best defence against painful, expensive dental work. It's a little tedious every day, but considering the consequences makes it feel worthwhile.
3: Exercise. A little more than you're doing right now. With use-it-or-lose-it muscles and a sedentary lifestyle, that adds up to lose-it pretty quickly. If you can structure your life so that you're walking or biking for your daily commute, you build in automatic activity.
4: Eat well.
5: Don't drive tired. You're already smart enough not to drive drunk. In a pinch, a catnap at the side of the road is better than the alternative.
6: Shots. Help your immune system fight off disease by keeping your vaccines up to date.
Stay healthy. Stay safe.
