Reduce further weight

Now my weight is around 70.+ kg from 72kg. I try to eat less and after looking at dad's case, it is better to be healthy and not fall down in your golden years. He got a concussion and blood clot in his brain and was babbling nonsense, until the neurologist and neurosurgeon gave him medication to dissolve the blood clot. He is doing very well now and positive about going back home to recuperate. I just wish him quality life in this aged situation at a ripe old age of 81. He's still able to do things himself, but is now wearing diapers as he could no longer control his bladder and such.
