How to gain weight fast

A lot of information is available online on how to lose weight but not much has been written about how to gain weight. If you are one of the people who find it difficult to put on some weight read on.
I once conducted a quick search online to find out how I could gain weight since I needed to start body building exercises . The advice I got was to eat small  frequent meals per day. It did not work! For most people, another reason to add some weight besides body building is just to look good. To accomplish that you do not need a special diet.
I found that from consuming 500ml of soda daily I exponentially increased my weight without greatly changing my diet. You can try it as well and see if it works for you.

Hide your phone recordings from music players

Have you ever played music loudly from your phone and out of the blues you start to hear a call recording you made sometime ago. The conversation was supposed to be private and suddenly a lot of people heard it loud and clearly from your bluetooth speakers. It is embarrassing, isn't it?

Instead of deleting your recordings to avoid embarrassment you can simply tell the music players not to show or even play your recordings. I am a song writer and whenever I get inspired I compose a song usually by singing out a few words loudly which then form a basis for my composition. I can not do without a sound recorder on my phone. But since the songs would be unpolished, I need to keep them from the public to avoid unnecessary criticism on something I might eventually choose to discard later.
ES file explorer makes the process of hiding your private files easy. Simply open the file manager and head to the recordings folder and click the menu button and select the create file option. Name t…

The best energy drink on the Zimbabwean market

I have tried several energy drinks that are available on the market so far and there is one that has now become my favourite. It is tasty and refreshing as well as affordable in comparison to what is on the market.
In most shops in Zimbabwe, you can choose from a variety of energy drinks namely, dragon, switch, sting and red bull. My favourite is the sting! It is by far the best product that the makers of Pepsi have come up with to date.

According to the description on the package the sting energy drink is a "caffeinated mixed fruit flavoured carbonated energy drink". It contains B vitamins and taurine. The fruity flavour comes from redberry and pineapple. Like most Pepsi drinks it contains non nutritive sweeteners but there is also some sugar I believe which makes the drink tastier.
Sting also comes in 330ml cans unlike most energy drinks which are package in 500ml containers. The price is amazing as it is lower than most canned drinks. Maybe it is because of Pepsi'…

Why Zimbabweans buy fuel from the black market

Many Zimbabweans turn to the black market when they need fuel for their cars. I sought to find out why considering that the prices on the black market are actually higher than on the formal market.
Fuel is sometimes scarce in Zimbabwe and when it is available one has to get into a huge que and wait for hours at a fuel service station before buying the fuel. In huge cities like Harare and Bulawayo, one has to ask around for information on the availability of fuel and may have to travel long distances to find  . the fuel. To avoid disappointment and inconvenience, most people prefer buying the fuel from the black market. That is not the only reason though.
Zimbabwe uses blended petrol. The fuel can be leaded or unleaded but it will definitely be a blend of ethanol and petrol. Many drivers believe that blended petrol does not last as much as pure petrol and that is the main reason why they would rather pay a higher amount of money for fuel on the black market.

Why you should install a mobile tracker

A mobile tracker can increase your chances of recovering your phone if you lose it. Most phones now come with a mobile tracking feature. I shall show you how to turn the feature on as well as explain the logic behind the mobile tracker.
To turn on mobile tracking, go to call settings from the phone app and select mobile tracker. Enter device password and set the your phone number. When you lose your phone you can send SMS commands to your number. The command can be to lock the phone or to wipe data completely.

If someone steals your phone you will receive an SMS on your number with details about your phone's location and the phone number of the new SIM card. This can help you locate and recover your phone.
