The beauty of moving naturally, i.e. walking and gardening, is they're low impact. You're less likely to fall down and break a hip. Setting up your life so you're nudged into general physical activity every day is a strategy for your entire life from age 10 to 100.

Your life, eventually, is the same way.

The people you surround yourself with influence your behaviors, so choose friends who have healthy habits.
