What can happen if I'm only at home?

If I'm only in bed at home and only on my laptop, can something happen to my body?

For example, I only go out 1-3 times a month and no more,

but this doesn't make my body rot or start to die right?

I'm 1.72m tall and male and weigh about 70kg

and the only problems I've had so far are my weak stamina, but I still have a lot of strength

You miss life

Thrombosis
To starve
More likely to die of thirst
you pee
the muscles decrease
your sitting position brings you pain

He only misses other experiences, but not life.

Well if you just lie around you will quickly lose your muscles.

How old are you?

93?

Just sitting around leads to many degeneration processes in the body. Tendons shorten, your posture becomes wrong, bone density decreases, muscles become weaker (including those from the heart), the elasticity of your blood vessels decreases, your skin is not optimally supplied with blood, which in turn leads to increased skin aging and your mental health also suffers, When these effects become noticeable now depends on extremism, those who do moderate sports 1-2 times a week and otherwise only sit around can protect themselves relatively well against the negative effects of sitting.
