I lived in a city with the highest density of 7-11s per capita. There was a 7-11 at almost every street corner. 7-11s in the US are day and night from those in Japan, Taiwan and Hong Kong. Can you imagine you could pay your utility bills, print documents, fax and even have a full wifi cafe experience all under one roof? In Japan, Lawson is probably more popular though.
Any form of exercise helps. Do not think of one second that it's only for your body -- it's equally important for your mind. I used to ride by bike by the coast every night, 365 days a year, 20km loop for exactly 40 mins. I couldn't have survived all the stress from work without it. Absolutely a lifeline. Don't keep reading my thread, go for a walk!
