For most realistic collapses, or rather declines, I think it is best to prep yourself and your home rather than bug out. I would own a house and land rather than rent an apartment. Even a 1/4-acre suburban plot can help. Make sure the land is safe, e.g, not on a historical flood plain or marsh. I notice most new houses don't have chimneys, they are entirely dependant on oil/gas/electricity for heating, so try and at least get a house with a wood stove so you have alternative heating when the electric cuts. Have physical security such as strong doors, but keep it unobtrusive, don't make it look like you are hiding/protecting something, e.g, have prickly bushes rather than barbed wire. Most importantly, stay fit and healthy.
Do common-sense prep before any wild scenario; get rid of debt first, pay off your house and car asap. Have rain water butts for water and solar/wind for electricity. Have alternative cooking means if the electric cuts, e.g, I keep a gas camping stove. Maintain a kitchen garden; learn to farm, rotate vegetables, maybe even keep a few chickens. Keep at least a 4-week stock of commonly used items, everything from food to medicine (especially prescriptions) to toilet roll and then rotate the stock to keep it fresh. Have non-electrical entertainment such as books, weights, arts, crafts, games, etc, the garden should keep you busy anyway. All this benefits you even if there is no collapse.
I also carry a bag that has a few items such as physical cash, water, chocolates, raincoat, phone battery, etc, enough to walk home from most places I go if I need to. Consider getting a bike with panniers. Always wear comfortable shoes.>>1594388
This. But it's not easy to find in such a brainless consumerist world. Especially in such a pampered and sheltered society like the UK, where people increasingly and voluntarily just leave things to the government. Any UK prep/sustainability forums I've been to is very slow or dead. Even my family mocks me.
