We just need to be healthy and have no sickness.
And with a good physical condition.
Of course if Your age is not too old and You must have discipline for Yourself .
If we have all these things and we are in good health.
We can learn anything and do everything with our own bodies.
For everyone there is of course a different time limit for to learn.
Because one learns easily and others need more time.
The muscle development is different for everyone , but everybody needs it.
Because without muscles and suppleness it will be difficult to train.
But we still can learnt with our good persistence.
It will not be easy and also get a lot of suffering but it is still possible to do so.
It will also build your self confidence for a better feeling.
You will earn self-respect for each victory You have.
