Since the DISEASE officially began in March，we've been told staying home is the best way to avoid catching Covid-19.But being homebound（居家隔離）for so long affects the body，weakening the heart and lungs and even damages the brain. （1）BB.This is what half a year of staying home can do to your body.
A week homebound，whether you are working，eating or sleeping，seems to give you a sense of comfort.（2）AA.That's because it can take months to build muscle and just one week to lose it.When you lose muscle，you're not necessarily losing shape，but you are losing strength.The stronger we stay，the easier it is for us to live longer.
If you're not exercising，you're not raising your heart rate.And when your heart isn't pumping as hard，it gets weaker.（3）FF.Many patients have felt their breathing function become worse，because they're no longer conditioned to exercise.Exercise is the only key to improving both heart and lung function.If it's not safe to leave the house，doctors recommend dancing or finding household objects for home strength training.
（4）CC.Exercise produces certain chemicals in the brain that break down toxins in the blood and even prevent them from going to the brain，where they can kill brain cells.
The effects of homebound are hidden-like the DISEASE，the physical reactions after months of staying home often aren't obvious until they become harmful or extreme.Keeping your mental and physical health while staying home requires some work，but it's a better preparation for uncertainty until Covid-19 is over.（5）EE.
A.But actually，it can ruin hard-won fruit.
B.The effects may stay with us beyond DISEASE's end.
C.This kind of lifestyle can slow your brain，too.
D.Possibly，you can work out in the gym.
E.And when it's safe to live fully again，you'll be prepared.
F.The same thing happens to your lungs when you're inactive.
G.Hopefully，the day will come when the DISEASE is swept away.
