I love the outdoors but I never thought of the hitchhiker.
It is better to just stay home and yak on forums.
Exercise is a must, but difficult. Here on France a person can take an hour exercise outside and stay within 1km of home, either alone or with people living in the same household. If you meet people on your walk, you should not stop and chat (chatting is a french obsession) but stay at least 1 metre away from them. You must also carry a self certified form with the date and time you left home. Any police officer can check the form and fine you of you don't adhere to the rules.
That one hour walking in the forest or by the river with the family os what is keeping us sane.
