I've learned how to make lacto fermented veggies - mainly sauerkraut or kimchi type mixes. These are vegetables fermented in the old way, without boiling /pasteurizing. The idea is that they contain loads of probiotics/vitamins/digestive enzymes. There have even been mutterings about anti cancer properties but I've no proof so don't yell at me
Apart from the supposed health benefits, this is also a great way to keep veggies, as if you do it correctly they can keep for years.
On a similar line, I've learned how to make kefir - a similar probiotic rich substance, but a drink. Also I'm making yoghurt..probiotics again. You probably get the idea by now.
Another prep I've introduced is learning yoga. Can I just mention yogatoday.com (I'm not affiliated or anything) but they have a subscription service where you pay $9 (£5.40ish) a month and get access to amazing yoga classes - choose from starter/beginner/more advanced. The brilliant thing about this site is that most of the yoga is filmed outside, in the stunning surroundings of the Wyoming mountains. It's worth it to just look at the scenery, never mind the yoga! They have a free trial month.
So, I hope that gives someone some ideas
