At least 8 hours of sleep a day is necessary to stay healthy. However, the busy schedules in today's world make it difficult for many people.

The brain needs those precious hours of sleep to function properly, that's why your reaction time is incredibly poor after a whole night spent studying for a test or prepare for a big presentation.

Your brain runs a 24-hour internal cycle. All the events spent in the day are stored in its short term memory, and during your sleep at night, they are backed up to its long term memory. When you don’t sleep the short-term memory fills up, just like a hard disk. You are going to face some extreme buffering and performance issues.

Your reaction time can dramatically increase when you wake up feeling fresh, after a good night's sleep.

Walking offers both physical and mental benefits for the body. Also, unlike HIIT, walking will not stress your body, which translates to an increased fat burn ratio.

The reason for this is that low-intensity workouts like walking use more fat than calories for energy.

Walking is especially good for women because the first area from where fat disappears is the abdomen – something all women want.

Stress elevates the level of cortisol in your body. Elevated cortisol rapidly reduces testosterone in your body. Think of it as a see-saw, when the body’s cortisol level goes up, the testosterone level falls, and vice-versa.

Stress, and consequent high levels of cortisol result in weight gain, and storage of harmful body fat around the organs. These also adversely affect your body’s testosterone levels.

To remedy this, try to keep away from stressful situations the best you can. Consume whole foods rather than fried foods and other junk/processed foods. Get regular exercise and get a good night’s sleep. All of these, over time, will help improve your overall health, as well your body’s testosterone levels.

This can be a little tricky, but it works like a charm. Let’s say you need to paint your room and would like your friends to help you out.

Now, they may be reluctant. But you could subtly slide in something that could motivate them to join you. For example, tell them that since you’d be tired after painting the whole day, you plan on chilling later with some booze and pizza. If they like booze and pizza, they’ll likely tag along. If they don’t like booze and pizza, then you should look for new friends anyway.

If you want smaller portions of rusks, Woolworths cut method would be affective. Place the dough mixture evenly into the greased pan over the baking sheet. Now put the pan into the oven and bake for about 20 minutes at 350 degree. If a toothpick comes out dry, your rusk is baked. Let it cool down and then cut down in smaller portion slices with a sharp knife. As the portions are smaller, the slices will come out clean.
