Each weekend, we’ll sort out your plans for you. These are the things we think you should browse, watch, read or do over the next couple of days. This weekend, read how the humble sandwich consumed Britain, find out how your online shopping habit is fuelling a robot renaissance, see the top 10 most followed models on instagram this year, find out where the 'new' Seven Wonders of the World are, get some ideas on what to do in Sydney this weekend, and check out why every surfer should shape their own board (at least once).
