Here’s how to keep up your stamina when it’s being tested.

• Like at a four-hour, standing room only concert. According to the journal Circulation, if you feel faint, you’ve got to get your blood flowing and ward off lightheadedness. So as you’re standing, cross one thigh over the other and then tense your leg, abdominal, and rear-end muscles for 30 seconds.
• So let’s say the endurance event is a lavish seven-course meal. Ed Jarvis, a champion competitive eater says, don’t skip lunch. Fasting will just make you want to stuff yourself later. So, eat normally before the big dinner. Then, once you sit down for the big meal, keep your water glass handy. According to German researchers, drinking two eight-ounce glasses of water during dinner can boost your metabolism by 30%. Watch your alcohol intake. Drinking two glasses of wine could make you eat 22% more than you otherwise would have. That’s according a study in Physiology and Behavior.
• So what if the endurance event is a long relationship talk? To keep your stamina up, start with coffee or tea. It’s endearing – and a recent study found that people judged others as more generous and caring if they held a warm beverage. Also, if your girlfriend wants reassurance, use the word “remember” often. According to psychologist Jeffery Bernstein, acknowledging your shared memories shows you’re invested in the relationship.
