How do you feel about your body changing in your 30s?

I'm 32. My body doesn't look the same way it did when I was 24, and definitely not when I was 18.

I lost 23 kg in 3 years (83 kg - 60 kg and I'm 154 cm) I don't think the changes are just due to weight loss. My body seems to have lost so much elasticity. My stomach and my upper arms are bigger and more flabby. The whole skin on my body doesn't look as tight as it did. My body just looks older.

I'm not panicking. I'm so thankful that I lost weight. I feel comfortable with the changes and I'm content. However once I reach my goal weight (50 kg) I will get treatments at a medical center (not skin tightening surgery, but other minor non-invasive treatments).

How do you feel about this? I hope you're comfortable with it as well.
