Whether it's true or not, it's a great reminder about how stress affects our bodies. An immediate stressor will put you into "fight or flight" to deal with the situation immediately and effectively or to get you the heck outta there! But those stressors that come on slowly and accumulate over time are wreaking havoc in all systems of your body and you may not even notice until it’s too late.
So listen to the messages your body sends you. And respond. Do whatever you can to lower your stress: pray, meditate, practice yoga, play tennis, run, eat well, think positively, keep a gratitude journal, surround yourself with loving & happy people, etc. Don't wait. Please don't be the frog.
