There's a select few of my friends who are really serious about their privacy. They all use strong passwords for everything, many don't bother with online banking or use bill pay services, most don't use eBay or Amazon, and most don't have social media accounts or, if they do, they are very careful about what they post and very cautious about who they friend. They never use their home address online, they're cautious about giving out their phone number, and so on.
