Let’s imagine that you are walking outside, when rain clouds catch you by surprise and suddenly pour down on you. Assuming that you have no umbrella or anything to cover yourself with, is it best to run back home or walk back? Or to elaborate, should you walk and spend more time in the rain, or should you run, which means you will run into rain sideways?
There are two ways you can get wet in the rain: it will either fall on top of your head, or you will run into it from the side. The amount of rain that falls on your head is constant whether you are walking or raining, as the entire field you are travelling through is full of raindrops. Therefore, one would naturally think that running would not add much benefit as you run into more rain by moving faster, as you essentially hit a wall of raindrops.
But this is not true. No matter how fast you travel, the amount of rain you hit sideways is constant. The only variable that affects the amount of rain you hit sideways is the distance you travel. This is because the amount of raindrops in the space between you and your destination is constant.
Summarising this, the wetness from rain you receive is:
(wetness falling on your head per second x time spent in rain) + (wetness you run into per meter x distance travelled).
Since you cannot really change how far you are from your destination, the best way to minimise getting wet is to run as fast as you can to minimise the time you spend in the rain.
Then again, this is only the most practical option to keep you dry. If you are feeling particularly romantic or blue, then feel free to stroll through the rain, savouring the cold drops on your face (or wallow in the sadness that is your life).

Valentine’s day is the one day put aside every year, on the 14th of February, to celebrate the love between a couple. It is a rather controversial(?) holiday with many people contesting that it is the result of chocolate and flower companies conspiring to increase sales and that people should love equally on every day. The day is full of hearts and cupids and chocolate, making it the perfect day for couples to show off to the world just how much they adore each other, while single people put up a nonchalant face while desperately trying to distract themselves from the fact that they alone (there is also a statistic that states suicide rates peak during Valentine’s day).
February 14th was not always associated with romantic love. Originally it was a day honouring Saint Valentine of Rome (it is debated whether day honours him or another Saint Valentine – Valentine of Terni). In 1st century Rome, it was illegal for Christians to marry. Saint Valentine secretly performed weddings for Christians under threat of death (helping Christians was illegal too). He was eventually caught, imprisoned, tortured and killed.
As one can see, the story (and its ending) is not the most romantic one and Valentine was honoured for helping Christians rather than being involved in marrying people. It appears that the romantic association started around the 14th century in Parlement of Foules by Chaucer. Up until the 19th century, the only custom for Valentine’s Day was the giving of cards (or “valentines”) between loved ones. It was in the mid-1900’s when the practice of giving roses and chocolates arose (most likely due to advertising campaigns by companies for the commercialisation of the day), with the diamond industry promoting a custom of giving jewellery on Valentine’s Day.
Another not-so-lovely story related to Valentine’s Day is the infamous Saint Valentine’s Day Massacre of Chicago in 1929. In a conflict related to gangs and bootlegging, the South Side Italian gang led by Al Capone initiated a deadly attack resulting in the death of seven deaths.
