Well I'm not sure this will help from a business perspective but here it goes: my father is reaching 65 and he's retiring in a year or so. He's an electronics engineer (and I'm a comp. eng). He doesn't want to stop working, so an idea is to buy a small, cheap, country side property (around 20000m2) to grow easy crops and have a relaxed but active lifestyle. I'll learn some stuff to help him have an easier time managing said crops (sensors for soil check etc) so I'm looking for DIY easy stuff or cheap things.
