On the contrary of the common belief that your brain cells stop multiplying after the age of 14 you can trick your brain cells into a natural and healthy multiplying mode to regenerate lost ones.

According to media published studies almost every fun and pleasing activity is dangerous to your brain. But actually there are a couple activities which are not dangerous but having stimulating effects on your brain cells according to the Medical Daily.

Getting Rid Of Extra Calories

If you practice some self control when eating you are not only get thinner but according to the Mental Health Daily if you decrease calorie intake it evokes a kind of stress in the human body. At first it may sound bad, but in reality it promotes brain cell multiplication in your brain. But don't go overboard. If you decrease your calorie intake by 20-30% in one go the positive effect will be nullified.

Green Tea

If you don't want to play with calories there is still chance. A 2012 study have found that drinking green tea has similar effects. This could be related to the antioxidant called EGCG which helps to improve cognitive functions in the brain and prevents memory loss.

BlueBerry 

It is an other effective and enjoyable way of building new brain cells. Just add some blueberries to your diet. A 2008 study have found that these tiny but powerful berries contain such antioxidants that cause some changes in your blood flow.  These changes not only protects your brain cells but stimulating the growth of new ones. Blueberries also contain anthocyanin which enhances the signals from a brain area which is responsible of your memory.

Sex and other Anaerobic Exercises

Maybe the best news of all. In a 2010 Plus ONE Journal publication said that an active sex life promotes neurogenesis (growth of brain cells) in the hippocampus. The hippocampus is responsible for memory functions but also regulates our emotions.

For more conservative or elderly people good news is that not only sex but running also helps to grow more brain cells says Mental Health Daily. 

One 2014 Study shows that in those people who run regularly in their whole life there is less chance for alzheimer than peers who did not live and active life.
