Forget disastrous A-levels results or missing out on a place at university. Never mind years of wasted studying.
Students, you have bigger - and more painful - things to worry about on Thursday.
Your family and friends may be itching to know your results but their curiosity could leave you sporting a serious injury if you send too many text messages.
Your wrists could ache. Your fingers could cramp. Your neck could stiffen. And as 100 million texts are expected to be sent on Thursday, physiotherapists are warning that thumbs around the country will be sent into overdrive.
So, while most people are focusing on such trivial matters as Clearing or life after A-levels, we thought we should pass on this very important health warning issue by the Chartered Society of Physiotherapists.
Tip 1. Make the most of your phone's predictive text function to take some of the load from the poor little workhorse that is your thumb.
Tip 2. Don't text on the run. Instead, support your arms on a chair or table to take some pressure off your neck.
Tip 3. Be ambidextrous. Swap texting hands regularly.
Claire Doherty, of the Association of Chartered Physiotherapists in Occupational Health and Ergonomics, issued this warning: "Though highly mobile and great for manipulative functions such as grasping, the thumb is not a very dextrous digit and can be prone to overuse, particularly when using one hand to grasp a phone and the thumb to activate the keypad.
"Mobile phones are not ergonomically designed for excessive text messaging and too much can result in pain and swelling of the tendons at the base of the thumb and wrist."
We welcome any other tips to keep thumbs fit and healthy on A-level day. Of course, when you post your comment please be sure you are sitting up straight, your wrists supported and you take regular screen breaks.
