How can I quickly catch a cold tonight on purpose?

It takes 12-36 hrs after contact with any virus/bacteria before you begin getting any symptoms. U can sleep with ur mouth open to cause a sore throat, this isn't permanent (not a virus just your throat drying out causing it to be sore). When u wake up in the morning it will hurt. Plug ur nose with tissue before u go to bed and u will wake up with a sore throat.
