One thing that really gets on my nerves is people spitting on the streets! I fail to understand whether they are just plain uncivilized or uninformed about how the act only helps in spreading diseases.
Why do our kids need to be protected from flu? Isn't that something only for the cold western countries who have long, cold, below-zero winters? That's what I thought until I learnt that India's tropical weather facilitates circulation of viruses around the year, unlike the West, which sees a peak only during winter.
