AEDs Arrive. Around 1980, the AED (automated external defibrillator) debuted. The 'automated' part is what is really exciting. Now people with only minimal training can successfully revive VF victims in the field, even before Emergency Medical Services personnel arrive.
Sensitivity has many shades of meaning but most relate to your response to your environment â either physical or emotional. Sensitivity to cold means youâre quick to notice the slightest chill â in the air or in another personâs actions. A sensitivity to pollen means youâre sneezing any time itâs in the air â you just always seem to react to it. Itâs the same with emotions â sensitivity means you pick up on the feelings of others.
With sensitivity, you may feel pain when consuming hot, cold, or sweet drinks or food, or even when breathing cold air. It is normal for teeth to be temporarily sensitive after an adjustment, but let your orthodontist know if you have chronically sensitive teeth.he roots of your teeth, which are not covered by protective hard enamel, contain thousands of tiny tubules leading to the tooth's nerve center (the pulp). When exposed, these tubules allow stimuli â such as hot or cold food â to stimulate the nerve in your tooth, causing the pain you feel.
