We bet that lady, who helped a lost tourist and also spared some change for a homeless man (bless her), wasn't thinking too much about increasing her karma levels. And by acting selflessly, perhaps she doubled the value of her good deeds.
While we doubt that qualifies her to win the million-pound jackpot (although you never know), we do think she'll get back a ton of positive energy, or at least a seat on her busy train to work.
To find out what your karma level is and whether you're behaving altruistically, we've designed the Karma Calculator. Let us do the maths, while you do the deeds.
